Introduction: The purpose of the lab is to study the effects due to magnetic fields in motion and also to determine the qualitative features of electromagnetic induction.

Procedure:
1. For the Part 1 of the lab, a solenoid was connected to a galvanometer, as shown in the data and calculations. First, the North pole was inserted into the coil, then in the opposite direction, with the South Pole first. Then, the magnitude and sign of the deflection on the galvanometer was recorded in μAmps. Also, an exact sketch is made of the solenoid, the direction of the velocity, the induced magnetic field, the induced current and the magnetic polarity of the solenoid induced in provided in the data and calculations portion of the report.
2. The magnet was inserted again following step 1, but with a faster speed and everything sketched again. Then, The South pole was inserted first and step 1 followed again for both, slow and fast speed.
3. For Part II of the lab, an electromagnet was constructed with the power supply off. In this set up the primary coil had a larger diameter wire and

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...

The standard deviation from length, diameter, and mass were 0, .0819, and .041 respectively. The measurement for length was probably the least precise measurement taken. We used a meter stick, but kept getting the same measurement, probably due to the meter stick not being very precise.

Physics Measurements Lab Report

...Lab #1 Measurements 31 JAN 2013 Introduction In this experiment we will explore measurements, the uncertainty of measurements and the effects of the uncertainties on the quantities calculated from the measured values. In Part I: Reaction Time, we will measure reaction times by having one student drop a meter stick through the hands of a second student. The second student will grab hold of the meter stick when he perceives it to start moving. The starting distance will then be subtracted from the final distance and this will give us our total length that the meter stick dropped. This number will then be used in an equation to calculate the reaction time it took the second student to catch the meter stick. In Part II: Density of Objects, we will pick a metal cylinder and measure its length using a meter stick. Based off our measurements we will estimate the uncertainty of each measurement. Then we will take diameter and length measurements of the same cylinder using a vernier caliper. Based off our measurements we will estimate the uncertainty of each measurement. Then we will use the balance to take measurements of the mass of the cylinder. Based off our measurements we will estimate the uncertainty of each measurement. Data and Analysis Part I: Reaction Time Data: All pertinent data collected will be found on Data Sheet 1-2. Analysis Part I: 1. The reaction times (t) were calculated using the equation __________________ where s = the distance that...

Physics Lab Report: Linear Momentum

...------------------------------------------------- Experiment 9 – Conservation of Linear Momnetum [Document subtitle] March 29, 2016 Engineering Physics 150 March 29, 2016 Engineering Physics 150 Objectives: The objectives of this laboratory experiment is to investigate the velocities and momentm of two carts before and after various types of collisions. Theory: * When objects collide and assuming there are no external forces are acting on the colliding objects, the principle of the conservation of momentum always holds. * For a two-object collision, momentum conservation is stated mathematically by the equation: * PTotali =PTotalf * m1v1i+m2v2i=m1v1f+m2v2f * When working with a complete inelastic collision, the two objects stick together after the collision, and the momentum conservation equation becomes: * PTotali =PTotalf * m1v1i+m2v2i=(m1+m2)vf * During this experiment, photogates will measure the motion of two carts before and after elastic collision. The cart masses can be measured by using a simple mass scale. * Then, total momentum of the two carts before collision will be compared to the total momentum of the two carts after collision. Equipment: 850 Universal | Dynamic Track | Two dynamic carts | Two picket fences | Mounting brackets | Mass Balance | Mass Bar | Two Photogates | Data: Part A – Elastic Collision with approx. equal masses: Trial | V1 i (m/s) | V2 i (m/s) | V1 f (m/s) | V2 f (m/s)...

Figure 2: Circuit Diagram of Hydraulic system 4. Mathematical Modeling of the Components 4.1 Modeling of Valves and Actuators The input to the system is the movement of the valve xi. This allows the flow of oil into the cylinder of Q m3\s which makes the cylinder move a distance xo [6]. Assuming constant supply pressure the flow rate is directly proportional to the valve position, Q=kv.xi (1) Where kv is the valve constant and examining its unit, it would be m2/s and area of the piston is m2. Thevelocityof theactuator is v =dx0/ dt and this is related to theflowand the piston areaby the law of continuingthat Q = kv.xi=A.dx0/dt (2) Changingto a function ofs this becomes, kv.xi=A(s).x0 (3) G(s)=x0/xi(s)=1/(A/kv)s (4) G(s)=1/TSwhereT=A/kv (5) By using the values of piston and cylinder area it was found that G(s)= 1/0.2945 s. 4.2. Modeling of Direction and Flow Control Valve A spool valve used for metering purposes controls flow rate by throttling. Each port in a valve that is partially closed by a land on the spool becomes a control throttle.The rate of flow of fluid through such a valve depends on the spool displacement from the null position “x” and on the pressure upstream and downstream of the valve. One way of representing the flow rate “q” through a valve is q = kq.x-kc.pm...

...Takako Hirokawa, Noah Finkelstein, and H. J. Lewandowski† Department of Physics, University of Colorado Boulder, Boulder, CO 80309 (Dated: March 4, 2014) In response to national calls to better align physics laboratory courses with the way physicists engage in research, we have developed an epistemology and expectations survey to assess how students perceive the nature of physics experiments in the contexts of laboratory courses and the professional research laboratory. The Colorado Learning Attitudes about Science Survey for Experimental Physics (E-CLASS) evaluates students’ shifts in epistemology and affect at the beginning and end of a semester. Also, at the end of the semester, the E-CLASS assesses students’ reflections on their course’s expectations for earning a good grade. By basing survey statements on widely embraced learning goals and common critiques of teaching labs, the E-CLASS serves as an assessment tool for lab courses across the undergraduate curriculum and as a tool for PER research. We present the development, evidence of validation, and initial formative assessment results from a sample that includes 45 classes at 20 institutions. We also discuss feedback from instructors and reflect on the challenges of large-scale online administration and distribution of results. I. INTRODUCTION Laboratory courses offer significant opportunities for engagement in the practices and core ideas of science. Laboratory course environments typically have apparatus, flexible...

...Lab Research Report SCI 110 January 27, 2014 Strayer University Lab Research Report Research in the physical sciences has often been limited by our abilities of safety observing and studying the phenomenon in question. Even before the thought of microscopes, it would have been impossible to comprehend the composition of the most basic cells. The exact issues are the current issues in the field of physical science today, but it’s particularly true in the world of physics. While new technologies exist to measure phenomenon, it is not always safe to do so in the field that deals with radiation, unstable compounds, particles and atoms. As a result, the technology that we have in the field of physics, but across the board in the physical science field of astronomy, chemistry, physics and earth science. Challenges in Measurements Over the years there have been many adventures that allow for direct measurements within the field of physics, there are still many obstacles and challenges to making direct observations. Physics is the study of energy and matter and the interaction between-both of which are impossible to observe with the naked eye. The first major challenge in making direct measurement in physics is the size of the particles being studied. To solve this issue, physicists study these particles indirectly through things like associated radiation, their energy, or the displacement of other atoms. Almost all measurements that have been made on atoms or...

...Phvsics Lab Report Format (Sample Report Attached) General Remarks: Writing a lab report is the only way your TA will know what you have done during the lab and how well you have understood the process and the results. 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...

Even with the tools that exist it is not always possible to safely do in a field that deals with atoms, particles, radiation, and unstable compounds. The technology in the area of physical science makes it very important on how much is learned and studied in the fields of astronomy, chemistry, physics and even earth sciences.

Physics is the study of energy, matter and the interaction between the two, which are impossible to observe with the naked eye. One common thing the field studies is energy creation to non-particles, all of the most recent discoveries in subatomic particles and the origins of the universe have all creative methods to study things that are extremely tiny. This would be the first major challenge to making direct measurements in physics. To avoid this problem, physicist usually studies these particles indirectly through things like associated radiation, energy, or the displacement of other atoms and/or compounds. Every measurement made on atoms or subatomic particles has caused indirect measurements (Kross). There are certain measurement tools whose...
