What determines which conservation laws apply in the collisions? Explain. If you were able to measure the total kinetic energy during an elastic collision, you would find that it is, or is not, conserved. Explain. enoladio JonesionlLINEAR COLLISIONS - MOMENTUM AND ENERGY OBJECTIVE-to observe linear collisions on the air track and study the relationships between momentum and kinetic energy before and after collisions of different types. BACKGROUND-In this experiment you will be using the air track, photogates and the timer to measure the velocities of the carts before and after collisions. Each photogate can record two velocities. Play with the carts and be sure you are aware which velocity is which on the timer display. Note that these are velocities and that you will have to record direction, i.e. which velocities are positive and which are negative. The timer can't do everything for you. Before starting, be sure the track is level and check the effects of friction by pushing a cart and allowing it to move through both gates. DO NOT push the gliders faster than about 80 cm/s as your results will not be accurate. OBSERVATIONS: Be sure to record your observations in an organized chart, in which you can clearly see the results from each part of the lab.
