multiple choice question
the same word completes each of the blanks in this definition: the impulse-____ theorem states that the impulse on an object equals the objects final __ minus the objects initial ____. which word should replace the blanks?

• work
• energy
• velocity
• momentum

Explanation:

The impulse - momentum theorem states that the impulse applied to an object is equal to the change in the object's momentum, which is the final momentum minus the initial momentum. Work is related to energy transfer, energy has different forms and the work - energy theorem is different, velocity is a part of momentum ($p = mv$) but the theorem is about momentum change. So the word that fits all blanks is momentum.

Answer:

D. momentum
