... If an object is in motion, then we can talk about its velocity, which is the rate of change of the object’s position as a function of time. Thus, at every moment in time, a moving object has a velocity, so we can think of the object’s velocity as a function of time! This in turn implies that we can ...

Momentum and Collisions
... Inelastic collisions: momentum is conserved, but kinetic energy is not. When 2 objects collide and stick together, the collision is PERFECTLY INELASTIC; in this case, their final velocities are the same. For perfectly inelastic collisions, m1v1i + m2v2i = (m1 + m2)v2f ...

Objects may be thought of as lazy because they don't change their motion unless forced to do so. • The tendency of an object to resist any change in its motion is referred to as its inert ...
