Question

One similarity between work and power is that in order to calculate both you must know_______ Choices: time.. . velocity.. . energy.. . force.

Answer 1

Answer:

The answer would be force bc in the previous question in the test it said to find power u need: force and velocity  and to find work you need force and distance.

Explanation:

just take quiz, hope that help:)

Answer 2

There are several types of work. Let’s talk about mechanical work: W = F*d So you need to know the force and the distance. There are several ways to calculate the power. First: P=W/t So you can calculate it like that if you have already calculated the work. Remember W is F*d, so: P=F*d/t Remember d/t is also velocity: P=F*v So you can also calculate the power if you know the force and the velocity, with no need to know the work or the distance. So in both cases we have a formula that requires to know the force.
