Linear Momentum - 1527 Words

Abstract: This experiment studies the conservation of linear momentum through a carefully calculated collision. Two gliders were used on an air track with different weights to demonstrate what would happen as gliders with varying masses collided into one another. Throughout the experiment the measured values of the momentum before and after the collision were used to calculate the total momentum conserved. Introduction: The question of whether or not momentum is lost or conserved during a collision has been a topic of interest for many years. When two objects of equal mass or varying masses collide what is the outcome? The gliders are used to vary the weights and the air track is used to take away all variables of friction that could†¦show more content†¦This velocity was multiplied by the mass of the glider to calculate both its momentum before and after the collision. There were three different situations used in which the weights of the incident and target gliders were either equal or different. When the two masses are equal, the velocity should be exchanged from the incident glider to the target glider. Therefore, the incident glider takes on the velocity of the target glider and the target glider takes on the velocity of the incident glider. When the incident glider has a mass greater than the target glider, the target body takes up a velocity in the opposite direction that is twi ce the incident glider. After calculating the velocities and momentum of each collision, the percent uncertainty was calculated by gently pushing a glider through two photo-gates and recording the velocity of the glider through each one. Using the following formula, we calculated the percent difference which is also the percent uncertainty in our speed measurements: . Using case 2, we calculated ratios of mass and velocity for each configuration. Using the following formula, we compared the ratio of mass and ratio of velocity. We compared the ratios to see if momentum was conserved by seeing if the ratios agree within three times the percent uncertainty in the velocities. .

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.

The camera was positioned so it wasRead MorePhysics Of The Field Of Medicine1381 Words   |  6 Pageskinetic energy would be conserved in this collision. A collision is classified as is momentum being conserved from one moving object striking another object. There are different forms of collisions that we learned about, inelastic and elastic collisions. In an elastic collision kinetic energy in the system is conserved, and in an inelastic collision kinetic energy in the system is not conserved.

The idea of the slap shot is to â€Å"convert the large amount of angular momentum carried by the player and the stick into li near momentum for the puck† (Hachà © 82). Because this is another form of a collision, we can use the principle of conservation of momentum. Momentum before the collision should be the same afterwards. For a slap shot, this would be calculated by I#969;1 = I#969;2 + mr2#969;3 where I is the momentRead MoreThe Law of Conservation of Momentum 1123 Words   |  4 PagesIntroduction Momentum is a vector quantity defined as the product of the mass and velocity of a body and is measured in kg.m.s. Momentum is conserved because when objects collide, equal forces are exerted on the objects but in opposite directions. The time for which the forces act is the same for both objects so the change in momentum must also be the same for both objects. This therefore means that if one object loses momentum, the other object must gain an equal amount of momentum. The total momentum remainsRead More The Physics of Football Essay1222 Words   |  5 Pagesinstance a wide receiver whose game depends greatly on being able to accelerate quickly will prefer to play on an artificial surface with less friction. When a player gets in the open field he may be capable of reaching his maximum momentum. When this players momentum is suddenly changed either with a great tackle or one hell of a hit the laws of physics concerning collisions, both elastic and inelastic, come into play. An elastic collision is a collision in which kinetic energy is conserved,Read MoreBlackwood Ballistic Pendulum1825 Words   |  8 Pagesby two methods: 1) employing uniform linear motion relations, the kinematic equations; 2) using the principles of conservation of energy and momentum. In this paper, we aim to validate the law of conservation of momentum. We do so by comparing results from two experiments conducted with a single ballistic launcher/pendulum apparatus. Hypothesis: The initial velocity of a ballistic pendulum can be determined using the law of conservation of momentum.
