Make student copies and let students fill in. Theory In this … The other end of the string is attached to a cart on an air track. Thus proving the conservation of mechanical energy. For the lab exercise, the theoretical expression derived using conservation of energy will be compared to an experimentally determined velocity of the glider. When a collision occurs in a closed system that has no force other than the force of momentum, momentum before and after the collision is equal. Note the difference between elastic and inelastic collisions. While the object rolls down the ramp the potential gravitational energy is being transferred into kinetic energy because of the movement of the cart. me. Regents Physics Lab Name: Date. This means that potential energy can become kinetic energy, or vice versa, but energy cannot “disappear”.
