SUMMARY

The formula for instantaneous power is defined as the product of force and velocity, expressed mathematically as P = F * v. This relationship indicates that instantaneous power can be derived by differentiating work done with respect to time. The general formula for power is P = W/t, where W represents work done and t is the time taken. Understanding these formulas is essential for analyzing the dynamics of moving objects.

What is the formula for instantaneous power if I have velocity and force? And what is the formula in general?
 
Physics news on Phys.org
Instantaneous power is the power of a ny object at an instant.
if you differentiate work done w.r.t time it will be the instantaneous power. If the givn velocity is instantaneous the
power=F*v
as p=w.d/time taken =force*dis./time
