For every action, there is an equal and opposite reaction.

For every action, there is an equal and opposite reaction

Mass times velocity

•Or p=mv

• It’s a lot like inertia, except it includes the effects of speed and direction

•Momentum can often explain outcome when 2 objects don’t seem to follow Newton’s 3rd. (there can never be any exceptions to a “law”)

Momentum in a system of interacting objects is conserved (stays the same) but is transferred

Ex 1: Who moves away faster? Does it matter who pushes harder?

Ex 2: How is the Earth affected when you jump?
