The impulse-momentum theorem states that

• The impulse on an object is less than the change in momentum it cause

• the impulse on an object is greater than the change in momentum it causes 

• the impulse on an object is equal to the change in momentum it causes 

• the force on a moving object is equal to the magnitude of the impulse.
