Final answer:
The impulse-momentum theorem states that the change in momentum of a system is equal to the impulse applied to the system.
Step-by-step explanation:
The impulse-momentum theorem states that the change in momentum of a system is equal to the impulse applied to the system. Impulse can be calculated by multiplying the force applied to an object by the time interval over which it acts. The change in momentum can also be expressed as the product of mass and change in velocity.
