## Linear Momentum

We have already described "the motion" of a moving object in terms of its Kinetic Energy

KE = ( ^{1}/_{2}) m v^{2}

Anotherway to describe "the motion" of a moving object is itslinear momentumMomentum = mass x velocity

p= mvThis means that

momentum is a vector; there is adirectionassociated withmomentum.Momentum and Kientic Energy both describe a moving object. They are somewhat similar. But they are different things different quantities. One of the differences is that Kinetic Energy is a scallar andmomentumis avector.Units?

Momentum has units of [ p ] = [ kg ] [ m / s] = kg-m/s

There is

nospecial name given to these units.
