Acceleration of a Cart

Purpose: The purpose of this lab is to find the relationship between acceleration, force and mass using a cart system.

Equipment:

• Motion detector

• Pasco GLX

• Cart

• String

• Pulley

• Hanging Weights & Metal Cubes

• Ramp

• Ruler

Procedure:

Experiment 1:

1. Weigh and record the mass of the cart (this will be kept constant for all trials) then the mass of the cart with all the hanging weights on top of it.

2. Take 1 hanging weight off the cart and attach it to the end of the string on the cart with the other hanging weights still on top.

3. Place the cart on the ramp in front of the motion detector.

4. Set the GLX using the correct units for the y and x axis for graphing. Then measure 20cm away from the motion detector, place the cart there and start the GLX and release the cart from 20cm at the same time. Stop the GLX and the cart few centimeters before the cart reaches to the end of the ramp for precise data.

5. Repeat steps 2, 3 and 4 by adding 1 hanging weight to the string of the cart with the previous hanging weight already on the string until all hanging weights are used and not left on top of the cart. Then record data.

Experiment 2:

1. Weigh the hanging weight and record the mass (this will be left constant for all trials).

2. Add a metal cube on to the top of the cart and weigh and record the mass of the cart with metal cube. Then place the cart on the ramp in front of the motion detector.

3. Set the GLX using the correct units for the y and x axis for graphing. Then measure 20cm away from the motion detector, place the cart there and start the GLX and release the cart from 20cm at the same time. Stop the GLX and the cart few centimeters before the cart reaches to the end of the ramp for precise data.

...In the 4-3 Lab, my group and I tossed a ball over a motion detector and recorded the measurements at five different points of the ball’s travel. Point A was at the beginning of its travel, right after it was thrown. Point B was about halfway up after the throw. Point C was at the highest point of the ball’s toss. Point D was at about the same height as point B, but was on the way down from Point C. Point E was right before I caught the ball at about the same height as point A, but on the way down from Point C. After calculating the three types of energy, Kinetic Energy, Gravitational Potential Energy, and Total Energy, for each point we noticed a few trends regarding the change in energy and the velocity the ball had during the toss. The first trend we noticed was that as ball’s velocity increases, GPE decreases and KE...

Television was fairly new and the screens were hardly there at all let alone being 60 inch plasma or LED units. If one’s family splurged or were well heeled they owned a fancy console TV, a huge piece of furniture who’s cabinet was made of very fine finished wood. Some even had flip top record players in them and ultra-fancy ones were super hi-tech stereo units.

...Abstract: In performing the Simple Harmonic Motion Lab, our goal was to determine the period of motion for objects performing simple harmonic motion. We did five trials of measuring the time it took a pendulum to make 30 complete oscillations. We divided that time by 30 to get the period and then took the average of all 5 trials, getting an average period of 1.88 seconds. To compare our results, and see if they were correct, we used the given equation for the period of motion that includes the length of the pendulum to calculate the period for the same pendulum, resulting in 1.87 seconds, which agreed with our earlier results. This shows that period of oscillations can be determined by length and gravitational acceleration, and doesn’t depend on mass.             In our other activity, we measured the period of an oscillating mass connected to a spring. We had a hanging spring, and hung mass to the bottom of it, each time measuring the change in length of the spring from the time before. To find the spring constant, we used the masses added to calculate each of their elastic forces, by multiplying each by gravitational acceleration, then plotting them with their corresponding spring deformation, and the slope of that graph was the spring constant, k, which was 8.22 N/m. Using this value, we calculated the period of motion for the mass of 0.1 kg using a different given equation than the one before, obtaining a period of 0.69 seconds. To verify our results, we used the VideoCom...

...bigger the beaker the more washers it would hold and need to make it Awash and the other way around. The data supports my hypothesis because, beaker 4 was the smallest so it didn't need many washer while beaker 2 was the biggest which needed 6 small washers, including 6 large washers. I think my data is not reliable because the graduated cylinder we used to measure the volume did not have the correct measurements so our data is a little off. This experiment is like something in the real world because a hot air balloon uses buoyancy to float and if there are too many people then the balloon will not have enough power to go up in the air. I think that my procedure is explained well because if I did not know the lab I could look at our procedure and do the correct lab. Our lab could be more accurate because if we had a better way to measure the volume of the beakers then we would have less...

...* Derive the expression shown on the site for a and s. (What the site calls s, is actually displacement or ∆x). Please note that s or ∆x is simply the distance from the starting point of the wagon to the light barrier. Remember, the wagon begins starts from rest. * Vary the values of M, m and , so that you have 2 different combinations. Make sure that  is zero (frictionless case) for the first combination and non-zero(case with friction) for the other. For example, for you first run, M could be 100g, m = 50 g and  = 0.00. For the second run, you could take M to be 100g, m = 30 g and  = 0.25. Remember, these are just suggestions, you can (and should) think of your own values. * For each run, make sure that you have a separate table showing at least 10 data points with s and t values). In order to get different data points, please shift the light barrier’s (LB) position, so that the value of s changes. Be careful that you do NOT change the value of any other parameter while doing this. In other words, your table would have currently have only 2 columns, with s and t vales. * To this table, add a third column showing t2 values. In other words, if your entry in the t column is 3.209s, the corresponding entry in the t2 column would be 10.3s2. * Use the table to make a graph of s vs. t2. Find the slope of this line. Multiply the value of slope by 2. This is your value of a from the...

...Lab Assignment 4: Types of Force Instructor’s Overview In many physics problems involving Newton’s laws of motion, you’ll see statements like, “assume a frictionless surface” or “neglecting air resistance…” In this lab we will be exploring both friction and air resistance, two resistive forces that are critical in the design of real-world products and systems. Understanding the effects of these types of forces is essential in the design of such things as aircraft, automobiles, braking systems, and countless other objects. This activity is based on Lab 4 of the eScience Lab kit. Although you should read all of the content in Lab 4, we will be performing a targeted subset of the eScience experiments. Our lab consists of two main components. These components are described in detail in the eScience manual. Here is a quick overview: * In the first part of the lab, you will measure the force it takes to pull objects of different mass. This experiment focuses on the effects of frictional forces. (eScience Experiment 1) * In the second part of the lab, you will investigate the effects of air resistance by performing controlled drops of coffee filters. Notes: * Please follow the instructions in this document for the air resistance experiment. * Record all of your data in the tables that are provided in this document. Take detailed notes as you perform the experiment and fill out the sections below. This document serves as your lab report. Please...

Chapter 2 Theory Motion: In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of velocity, acceleration, displacement, and time. Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to another reference frame. A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects in...

I will be measuring the distance and finding out the time . Distance will be changed however the size of the ball and the type of the ball will remain constant , The time will be then give me the value of gravity by the suvat equation ,where acceleration will be the subject . Background Knowledge.For  an  object  to  move,  a  force  that  is  greater  than  its  opposite  force  needs  to  act   upon  an  object.  Force  =Mxa  where  in  this  case  at  least  acceleration  is  due  tp  gravity  .   Every falling object accelerates at a constant rate and this happens simply due to the force of gravity ,so mathematically the distance “s” that the object is travelling is half the acceleration times of time squared additional to the initial speed and time .   Now , We are going to make a the subject of the equation .After making a the subject of the equation we find out that the acceleration due to gravity is twice the distance of Time Squared will equal to acceleration due to gravity . The answer should be somewhere close to 9.81m/s-2 Time  (m/s)   Distance(m)     The graph above shows the relationship between the two variables .In this experiment distance is the independent variable and Dependent variable is time .

...Name 2) Which color vector (arrow) represents velocity and which one represents acceleration? How can you tell? The green arrow represents velocity and the blue arrow represents acceleration. This is apparent because the velocity is reliant on speed and direction, while acceleration is reliant on the change in velocity. 3) Try dragging the ball around and around in a circular path. What do you notice about the lengths and directions of the blue and green vectors? Describe their behavior in detail below. I noticed that the green arrow points the direction I am dragging and stays relatively the same while the blue arrow fluctuates rather rapidly at a perpendicular angle of the green arrow. The velocity or green arrow is always pointing in the direction I am moving and since I am going a constant speed it stays the same length. The blue arrow is showing the acceleration due to the rotation and it fluctuates rapidly due to me being unable to create a perfect speed and circle around a focal point. 4) Now move the ball at a slow constant speed across the screen. What do you notice now about the vectors? Explain why this happens. When I move them in the same direction they are even/on top of each other. This happens because the velocity or direction and speed are constant making the acceleration constant. 5) What happens to the vectors when you jerk the ball rapidly back and forth across the screen? Explain why this happens. The blue arrow goes with the green the shoots in the...

Part of your lab experience should be learning how to organize and present your work in a scientific way. There is no framework that can be used as a "one size fits all", therefore this sample lab report should only be used as an example. Any lab report should have the following features: o It should be concise but should also contain the necessary details and well-developed explanations. It should be organized. You should enable the reader to quickly find the information he or she may be interested in. It should contain all the relevant information and reasoning. You should enable the reader to validate your conclusion. A possible way to achieve this is using the following framework: o o . o o o o . Obiective: State what you want to achieve in this experiment A formal way to do this is to state a question or hypothesis that you want to address. Method: You should include a summary of the lab procedure in your words; do not merely copy what is in the manual. This section should demonstrate your understanding of what exactly you measured and how you measured it. Data: In this section you should include the raw data you measured; generally, an estimate of the error should accompany all measured values. Be sure to present...
