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.
