Question

which of the following is correct
1)p=w/t
2)p=f.v
3)p=mgh/t
4)all of these​

Answer 1

All of the above equations are correct ✔️.

Detailed Discussion:

• Power is defined as rate of doing work, so the formula is : P = Work/Time = W/T

• Power can be medically derived as the scalar product of force vector and velocity vector. So, P = F × v

• Also, when and operator does work and moves a body of mass m from the ground to height h , the power will be : P = work/time = mgh/t.
