Also, the mass of the object is 5 kg. This formula is also called the mechanical power equation. It is the work/time ratio. P = power (w, or j/s) ∆w = the work done, or energy used (j) ∆t = the time taken to do the work (s) power formula questions: (power equation) also, we can rewrite the power formula.
