...Franke Horstmann Lab Report—Momentum Lab Survey Physical Science 09/09/2014 Abstract This experiment helped validate the law of conservation of momentum. The test was done by conducting two experiments with car A and car B, car A’s mass being known and car B’s mass unknown. Experiment A was done by sticking the cars in the center of the track and setting off the puncher then recording the car velocity. Experiment B was done by placing car B in front of the second photogate and car A at the start of the track, again the trigger of car A was set off and it collided with car B and the car velocity was recorded. Our results show momentum and kinematics methods show highly accurate results. Introduction Newton’s 3rd Law states that for every action there is an equal and opposite reaction. There were two experiments conducted in order to validate the law of momentum conservation. This law states that when there is a collision of two objects the total momentum of the two before the collision should be equal to the total momentum of the two objects after the impact. Materials * Car track with slots * 2 rolling cars * 2 Photogates * Weights * Data Acquisition Board * Computer with measurement software * 2 picket fences * Ruler * Balance scale Procedure In order to perform the experiment the car track and balance scale were checked in order to make sure they were well-adjusted so that the results were accurate.

...One copy of the lab report Physics 1030L/ Section 2 Conservation of Momentum Lab performed: 2/18/13 Report submitted: 2/20/13 Sample Calculations Results The magnitudes of the masses for the gliders before the collision were: mass XA1 is equal to 0.107m, and mass XB1 is equal to 0.101m. The magnitudes after the collision of the masses were: mass XA2 equal to 0.0890m, and mass XB2 equal to 0.0820m. The momentum of the masses before collision were: mass PA1 equal to 0.3737 (kg m/s), and mass PB1 equal to 0.3551(kg m/s). The momentum after collision of the masses were: PA2 equal to 0.3109 (kg m/s), and mass PB2 equal to 0.2886 (kg m/s). When considering the direction of the vectors the area of uncertainty is small when considering the area of both parallelograms of uncertainty, because the overlapping of the parallelograms is only a small portion of each. The momentum was partially conserved within the error range of the parallelograms, or the portion where they overlap. Conclusions 1. It is necessary that they glide on a cushion of air, so that they can avoid any friction which would slow down their movement and could possibly keep them from colliding. The friction would differ for each mass, and would change all the predicted values. If the masses were not on an air cushion, it is impossible to predict that the two masses would ever collide because of the differing frictions for each mass. 2.If the masses were...

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...

...|Lesson Synopsis: | This unit develops an understanding of electrostatics by the use of demonstrations, simulations, and modeling. The general theme is that the current model of matter consisting of electrically neutral atoms composed of charged particles is integral to the understanding of electrical forces. The lesson begins with traditional activities of charging objects by friction and comparing electrostatic forces to magnetostatic forces. The traditional experiments are explained in terms of the model of an atom, and the “attract and repel force rules” are explored and expanded. Devices to create, store, and measure charge are utilized in experiments. The formal theory of Coulomb’s law is introduced, and problems are assigned utilizing that theory. Elements of the historical development of electrostatics and planetary model of the atom are researched, and students have an assignment describing contributions of historically important scientists. Additional concepts of electric fields, potential difference, and properties of conductors and insulators are developed through experiment, demonstration, and discussion. TEKS: |P.5 |The student knows the nature of forces in the physical world. The student is expected to: | |P.5A |Research and describe the historical development of...

...Simple Harmonic Motion Aston University Engineering and Applied Science – Physics Lab Report 01/11/2014 Determination by simple harmonic motion of the acceleration due to gravity Introduction: A system undertaking simple harmonic motion (SHM) can be restrained very accurately. The period of the SHM depends both on the mass of the system and the strength of the force tending to restore the system to its equilibrium state). Oscillations are a common part of life, for instance the vibrations of a musical instrument which helps make sounds or the foundations of a car suspension which are assisted by oscillations. The main aims of this experiment was to determine if the oscillation of a mass which hung vertically from a spring; this oscillating system was used to measure the acceleration of earth due to gravity and to determine the accuracy of experimental results precisely. (http://www.pgccphy.net/1020/phy1020.pdf Theory: | | | Acceleration due to gravity The value of 9.8m/s/s acceleration is given to a free falling object, directing downwards towards Earth. Any object moving solely under the influence of gravity is known as acceleration of gravity and this vital quantity is denoted by Physicians as the symbol g.

...Joel Schwartz Final Paper - Draft 7/16/12 Professor Hoge English 1020 Animal Rights Activism: A Domestic Terror Threat Throughout the past two decades, extreme animal rights groups have claimed responsibility for hundreds of crimes and acts of terrorism, including arson, bombings, vandalism, burglary, animal release, and harassment. These crimes have caused damage costing more than one hundred million dollars. While some activists have been captured, animal rights terrorism cells, are extremely difficult to identify and most of the attacks remain unsolved. Although it has been overshadowed by Islamic terrorist threats since September 11, animal rights terrorism still remains one of the United State’s most active terrorist movements. This paper intends to explore the Animal Rights terrorist movement and prove that Animal Rights activists pose a significant domestic terror threat. An increasing number of terrorist activity in the United States has been carried out in the name of animal protection. Although no one has been killed in an attack, the increasingly violent nature of attacks suggests that someone will be proclaimed dead before long. Beginning in the 1970s, hundreds of groups in the United States have advocated for much stricter legal protection for animals. Change has been slow but incremental. Some activists have become frustrated by the pace of legislation, and have become violent. This violence has created an underground terrorist movement...

On August 5th, The Center for Science and Environment (CSE), an activist group in India focused on environmental sustainability issues (specifically the effects of industrialization and economic growth) issued a press release stating: "12 major cold drink brands sold in and around Delhi contain a deadly cocktail of pesticide residues" (See Exhibit 1). According to tests conducted by the Pollution Monitoring Laboratory (PML) of the CSE from April to August, three samples of twelve PepsiCo and Coca-Cola brands from across the city were found to contain pesticide residues surpassing global standards by 30-36 times including lindane, DDT, malathion and chlorpyrifos (See Exhibit 2). These four pesticides were known to cause cancer, damage to the nervous and reproductive systems, birth defects, and severe disruption of the immune system. 4 In reaction to this report, the Indian government banned Coke and Pepsi products in Parliament and state governments launched independent investigations, sending soft drink samples to labs for testing.
