Question

impulse = a change in momentum cfu
as the impulse on an object increases, what must also increase?
the inertia of the object
the frictional force acting on the object
the change in momentum on the object
the reaction force acting on the object

Explanation:

Step1: Recall the impulse - momentum theorem

The impulse - momentum theorem states that \(J=\Delta p\), where \(J\) is the impulse and \(\Delta p\) is the change in momentum.

Step2: Analyze the relationship

Since \(J = \Delta p\), if the impulse \(J\) on an object increases, then according to the equation \(J=\Delta p\), the change in momentum \(\Delta p\) must also increase. Inertia (\(m\)) is a property of the object related to its mass and is not directly related to impulse in this context. Frictional force (\(F_f\)) and reaction force (\(F_{reaction}\)) are forces that can contribute to impulse (\(J=\sum F\Delta t\)), but the direct relationship from the impulse - momentum theorem is \(J=\Delta p\).

Answer:

The change in momentum on the object
