Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it hasmomentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving.
Ex 1) A 5.0 kg mass has its velocity change from 8.0 m/s east to 2.0 m/seast. Find the objects change in momentum.
m = 5.0 kg
Vi = 8.0 m/s East
Vf = 2.0 m/s East
Δp = ?
J = Ft = mΔv =Δp
Δp = mΔV
= (5.0 kg)(2.0 m/s - 8.0 m/s)
= -30. kgm/s East
or +30. kg m/s West
