Momentum is a quantity that can be calculated by multiplying the mass and velocity of the object involved. Momentum is expressed by the letter p. So momentum equals mass times velocity or p = m x v. Therefore, if any object of any mass is not moving, its momentum is zero because its velocity is zero.
Velocity is a measure of how quickly an object moves. So, the velocity is the change in the position of an object, divided by the time. Velocity has a magnitude (a value) and a direction. The unit for velocity is meters per second (m/s)
V = (Xf - Xi)/t = Δx/t
<i>v</i> = velocity (m/s)
<i>xf</i> = the final position (m)
<i>xi</i> = the initial position (m)
<i>t</i> = the time in which the change occurs (s)
Δ<i>x</i> = short form for "the change in" position (m)
