One similarity between work and power is that in order to calculate both you must know_______ Choices: time.. . velocity.. . energy.. . force.
There are several types of work. Let’s talk about mechanical work:
W = Fd
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 Fd, so:
P=Fd/t
Remember d/t is also velocity:
P=Fv
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.
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.
