The impulse-momentum theorem states that
The impulse exerted on an object is greater than the object’s change in momentum
The impulse exerted on an object is greater than the object’s change in momentum
The impulse exerted on an object equals the object’s change in momentum
The impulse exerted on an object equal to the product of the object's mass and force
The change in an object’s momentum is equal to
the product of the mass of the object and the time interval.
the product of the force applied to the object and the time interval.
the time interval divided by the net external force.
the net external force divided by the time interval
A large change in momentum over a long period of time requires a small force.
True
False
