Laboratory V: Conservation of Momentum Problem #1: Perfectly Inelastic Collisions John Greavu April 17‚ 2013 Physics 1301W‚ Professor: Evan Frodermann‚ TA: Mark Pepin Abstract A cart was given an initial velocity toward another stationary cart down a track. The initial velocity of the first cart as well as the masses of both carts was varied throughout multiple trials. Velcro placed on the ends of the carts caused the cars to stick together after colliding. Videos of the collision and the seconds just before

Collisions in Two Dimensions Abstract: This lab was conducted to investigate the theories of conservation of momentum and kinetic energy in different types of 2D collisions. In order to do this‚ both an elastic and inelastic collision was conducted on an air table with pucks. A video was taken and analyzed to determine velocity‚ allowing for future finding of momentum and kinetic energy values. By finding these‚ it was possible to determine which kind of collision took place. With low values of

During a car crash‚ there are three different collisions that occur. The first one is the collision of the car and the opposing object‚ the second is the human inside the car and the car itself. The final collision is the ones that occur within the human body itself. BRAIN: The human brain is protected by the cranial cavity or the skull. The brain is suspended in a substance called the cerebral spinal fluid‚ which is denser than the skull itself. In a collision‚ the brain and cerebral spinal fluid begin

Lab: Momentum Conservation Abstract This experiment aims to test the law of conservation of momentum by using cart and track system. Procedure 1. Put two carts onto the track. 2. Hit the button on the cart so that they start to move at opposite directions. 3. Find the position where the carts hit the end at the same time. 4. Find the distance that each cart traveled. 5. Repeat step 1-4 with 500g and 1000g weights on one of the carts. Data and Calculation m1m2=x2x1

Angular momentum and its properties were devised over time by many of the great minds in physics. Newton and Kepler were probably the two biggest factors in the evolution of angular momentum. Angular momentum is the force which a moving body‚ following a curved path‚ has because of its mass and motion. Angular momentum is possessed by rotating objects. Understanding torque is the first step to understanding angular momentum.<br><br>Torque is the angular "version" of force. The units for torque are

Encoding Information with Light’s Orbital Angular Momentum Light is the future of communication‚ traveling at 3‚000‚000 meters per second‚ the cosmic speed limit of the universe. Its tremendous speed makes it optimal for data transmission. The conventional method to encode information in light is through amplitude modulation‚ i.e. light pulses‚ time division multiplexing‚ i.e. delaying the time light beams enter a channel‚ and wavelength multiplexing‚ i.e. multiple beams of light in one channel

Maggie Haas Reiter Honors Physic 8 March 2015 Background Information: Anything that has mass and is moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved‚ which means that “momentum before an event equals momentum immediately after‚ or pi=pf”. Since pi=pf‚ then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi)

Lab 5 Conservation of Momentum and Energy Abstract The physics laws governing conservation of momentum and mechanical energy were investigated by performing multiple experiments with differing conditions. Conservation laws state energy is to be conserved in systems with no net external forces. Two trials consisted of inelastic collisions and two trials consisted of elastic conditions. Photogate software helped decipher initial and final velocities in order
