momentum = mass times velocity (kg m/s)

Force = mass times acceleration (N)

Kinetic Energy = one half mass times velocity squared

Impulse = Force times time or the change in momentum "delta p"

mass, how much "stuff" an object is made of (kg)

velocity, speed and direction (m/s)

acceleration, change in velocity over time (m/s2)

time, measure of events (seconds)
