Collisions Inelastic Collisions Elastic Collisions Stationary Target Moving Target Collisions in 2-Dimensions (Glancing Collisions) Inelastic Collisions Collisions in which kinetic energy is not conserved. Initial kinetic energy is transformed into other types of energy (thermal‚ potential etc.) Total final kinetic energy is less than the total initial kinetic energy. If two objects stick together as a result of the collision‚ the collisions is inelastic. Even though the

validity of the conservation of linear momentum from three main different types of momentum‚ namely: head on collision of equal masses‚ head on collision on unequal masses and exploding carts. Theory In the 17th century‚ Isaac Newton was the one who realized that the momentum is conserved in collision. Momentum is the product of mass and velocity (direction). In the other way‚ momentum is also a vector so the direction is important to the determination of the total momentum of a system of objects. Furthermore

Collision Lab Simulation Purpose: To study elastic and inelastic collisions in one-dimension. Background Information: Momentum: is a measure of mass in motion. It is the product of mass x velocity. Conservation of Momentum: in the absence of external forces‚ such as friction‚ the linear momentum of a system remains constant. Procedure: 1.

✎ ✍ 5.2 ✌ Cramer’s Rule Introduction Cramer’s rule is a method for solving linear simultaneous equations. It makes use of determinants and so a knowledge of these is necessary before proceeding. 1. Cramer’s Rule - two equations If we are given a pair of simultaneous equations a1 x + b1 y = d1 a2 x + b2 y = d2 then x‚ and y can be found from d1 b1 d2 b2 a1 b1 a2 b2 a1 d1 a2 d2 a1 b 1 a2 b 2 x= y= Example Solve the equations 3x + 4y = −14 −2x − 3y = 11 Solution Using Cramer’s

initial momentum = final momentum assume a linear collision‚ since no angles are given 0.05kg*0.6am/S + 0 = 0.05kg*-0.2am/S + 0.03kg*v v = 1.3 am/S It should be noted that this data isn’t valid -- the larger mass marble will continue to have "positive" velocity after colliding with a smaller mass marble. Think Newton’S cradle. I suspect that the overall KEN has increased in this problem‚ a no-no (but I haven’t calculated it). initial momentum = final momentum assume a linear collision

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 change in momentum and kinetic energy that occurred in elastic collisions

1) Introduction This Lab is about conservation of momentum. It is to investigate the difference of momentum before and after collisions. Using the photo gates record the velocity of each cart‚ comparing momentum and kinetic energy to find the law. The experimental apparatus are two red carts in approximately same weight and a gold cart in lower weight than the red ones‚ a stable air track (blow a constant stream of air out through numerous tiny holes) with low friction and two photo gates. 2) Project
