Question

One similarity between work and power is that in order to calculate both you must know

a. time
b. velocity
c. energy
d. force

Answer 1

there is a lot of ways you can find power, and work too, but power more.

so in this case... it has to be force. i'm saying this because there is another way to find power and its: power = force x velocity

work = force x distance

do you see the similarity here? its force.

Answer 2

D.) In order to calculate both of them, we must know the "FORCE" on the system.
