To determine the power, which formula should you use?

There are several formulas for determining the power N in physics.

Let’s write the formula for the power of the body through work and a known time:

N = A / t,

where N is the power in watts;

A – body work in J;

t – working time in s.

There is also a formula for power through force and speed:

A = Fs

N = A / t = Fs / t = Fu;

where F is the force acting on the body in newtons;
u – speed in m / s.
