Collisions 11/14/07 Composite Discussion: The goal of this lab is to attempt to detect the conservation of linear momentum and angular momentum in the context of a collision. The conservation of energy should also be considered though it involves all forms of energy and can’t be tested. The results of the lab were as follows: - pxB = 438.882 g*cm/s +/- 17.904 g*cm/s - pxA = 397.991 g*cm/s +/- 11.271 g*cm/s - pyB = 326.53 g*cm/s +/- 21.38 g*cm/s - pyA = 354.532 g*cm/s =/- 19.385 g*cm/s - LzTB = 333.269 gcm 2 s -1 +/- 27.149 gcm 2 s -1 - LzTA = 1479.36 gcm 2 s -1 +/- 68.41 gcm 2 s -1 - KETB = 10896.4 J +/- 887.7 J - KETA = 9463.88 J +/- 437.64 J Linear momentum is defined as the product of an object’s mass and velocity. Mass in the equation is a scalar quantity and Velocity is a vector quantity, therefore it takes into account the direction. Angular momentum is the measure of the point to which the object will continue to rotate about that point unless acted upon by an external torque. Kinetic energy is the work needed to accelerate a given body to a given mass to its current velocity. Conservation of Energy states that the total energy of an isolated system remains constant in time. Conservation of Linear Momentum states that if the net force acting on a physical system equals zero, the total momentum of that system remains constant. Conservation of Angular Momentum states that if the net torque on a system equals zero,
