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

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

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

to study the principle of conservation of momentum in collisions using two bodies. We also calculated the amount of kinetic energy in elastic and inelastic collisions before and after the collision. Introduction: When bodies collide with each other‚ the total momentum p = mv‚ is always conserved regardless of the type of collision provided no external forces are present. There are two types of collisions. In an elastic collision‚ both the kinetic energy and the momentum are conserved. An inelastic

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)

information collectors. This will measure the acceleration‚ velocity‚ and position of the cart as it moves down the track. The most important measurement collected is the velocity; which will be used to calculate the momentum. We will also explore how mass impacts in the change of momentum‚ and if there can be a non-changing impulse between the two carts with different masses.

CONSERVATION OF MOMENTUM PRACTICAL WRITE UP AIM: To investigate if momentum is conserved in two-dimensional interactions within an isolated system. HYPOTHESIS: Without the effects of friction the momentum will be conserved in the isolated system. In all three experiments the momentum before the interaction will equal the momentum after the interaction. METHOD: An air hockey table was set up and a video camera on a tripod was placed over the air hockey table. The camera was positioned so it was

Quantitative Conservation of Momentum Name: ______________________________________ 1. Kim holds a 2.0 kg air rifle loosely and fires a bullet of mass 1.0 g. The muzzle velocity of the bullet is 150 m/s. Find the recoil speed of the gun. Momentum conservation equation: Recoil speed =________________ 2. If the girl in the previous question holds the gun tightly against her body‚ the recoil speed is less. Calculate the new recoil speed for the 48 kg girl. Momentum conservation equation:

The law of conservation of momentum states that momentum can neither be created nor destroyed; the total momentum of any closed system must remain the same. Momentum is mass times velocity. Thus‚ a ten pound object moving at 5 meters per second has the same momentum as a 2 pound object moving at 25 meters per second (for example). In order to alter the motion of one object‚ you have to transfer the momentum to another object. Now‚ this principle is not intuitively obvious‚ because we are constantly

What is momentum? Momentum of a body is defined as the mass multiplied by the velocity of this object. Momentum= m x v Momentum and Newton’s second law of motion: The resultant force is proportional to the change in momentum per a second. We know that force = mass x acceleration. So F (mv-mu)/t F m (v-u)/t = ma so F=kma Momentum is a vector quantity: Momentum has a direction as well as a magnitude Momentum and Newton’s first law of motion: An object remains at
