According to Newton's First Law of Motion . every action has an equal and opposite reaction
objects in motion will keep moving unless acted upon by force
objects at rest can start moving on their own
objects in motion stop moving once force is removed

Write the equation for momentum, first using symbols for the variables, then using words for the variables.
