Will you use more power running up the stairs or walking up the stairs?
Running up the stairs
Walking up the stairs
The same in both
What is the equation used for calculating power from force and velocity
Power = force/velocity
Power = force * velocity
Power = force + velocity
Power = velocity / force
What is the equation used for calculating electrical power
P = I/V
P = I + V
P = V/I
P = I * V
