The energy of motion is called: Kinetic energy. potential energy, inertial energy. Power. In an inelastic collision: momentum is conserved. kinetic energy is conserved, both (a) and (b). If the velocity of a moving object is doubled and its mass is cut in half, the kinetic energy of the object is; remains the same, doubled quadrupled, cut in half. When the net work done on an object is speed of the object is me on an object is zero; the...

Prove the following about two objects colliding elastically in one dimension. Note: each step helps with the next, and all of this is useful for 1D elastic collisions of two objects. (a) For an incident particle A of mass mA and a target particle B (mB), the initial (vA,o and vB,o) and final (vA,f and vB,f) velocities are related as follows: (b) If the target B is initially stationary (VB,0 -0), show that the final velocity of particle A is:...
