Answer to Question #178058 in Physics for Abdul Abduli

Question

Out of list below, select all of the options that are an impulse: *

The change in momentum

A net force acting for a certain amount of time

momentum final - momentum initial

Fnet * t

Answer 1

According to the definition of the impulse, the impulse is the change in momentum. Also, the quantity $F_{net}t$ is impulse. Therefore, all the options are true:

(a) The change in momentum is impulse.

(b) A net force acting for a certain amount of time is also impulse ($J=F_{net}t$)

(c) Momentum final - momentum initial is also impulse ($J=\Delta p=p_f-p_i$ )

(d) Finally, $F_{net}t$ is also impulse.
