Question

2 what is the impulse - momentum theorem?
the impulse of an object is inversely proportional to the change in its momentum.
the impulse of an object is greater than the change in its momentum.
the impulse of an object is less than the change in its momentum.
the impulse on an object is equal to the change in its momentum.

Explanation:

According to the impulse - momentum theorem, \(J=\Delta p\), where \(J\) is the impulse (\(J = F\Delta t\)) and \(\Delta p\) is the change in momentum (\(\Delta p=p_{f}-p_{i}=m(v_{f} - v_{i})\)). This means the impulse on an object is equal to the change in its momentum.

Answer:

The impulse on an object is equal to the change in its momentum.
