Power from Force and Velocity
Power from Force and Velocity
\[P = Fv\]
Variables
P = power (W)
F = force parallel to motion (N)
v = velocity (m/s)
Description
What is this formula?
The power-force-velocity equation calculates the mechanical power transmitted when a force acts on an object moving at a constant velocity.
When to use it
Use this formula when analyzing engines, motors, vehicles, conveyor systems, pumps, or mechanical systems delivering continuous motion.
Example
A motor applies a force of 1500 N to move a vehicle at 12 m/s.
Data:
F = 1500 N
v = 12 m/s
Formula:
P = F*v
Substitution:
P = 1500*12
Result:
P = 18000 W
Applications
Automotive engineering, electric motors, industrial machinery, transportation systems, mechanical power transmission, and robotics.
