Question

which of these quantities is impulse equal to? select all that apply. select all that apply a force multiplied by time elapsed. b momentum. c the change in momentum. d mass multiplied by the change in velocity.

Explanation:

To solve this, we recall the definitions:

• Impulse (\(J\)) is defined as force (\(F\)) multiplied by time (\(t\)): \(J = F \times t\) (matches option A).
• By the impulse - momentum theorem, impulse is equal to the change in momentum (\(\Delta p\)): \(J=\Delta p\) (matches option C).
• Also, \(\Delta p = m\Delta v\) (mass times change in velocity, matches option D).
• Momentum (\(p = mv\)) is not the same as impulse (eliminates option B).

Answer:

A. Force multiplied by time elapsed., C. The change in momentum., D. Mass multiplied by the change in velocity.
