Power (P) = Force (F) * Velocity (V)
Here's a breakdown:
* Force (F): This is the force applied to the body, measured in Newtons (N).
* Velocity (V): This is the body's velocity, measured in meters per second (m/s).
* Power (P): This is the rate at which work is done, measured in Watts (W).
Important Considerations:
* Direction: This formula assumes the force and velocity are in the same direction. If they are not, you need to consider the component of force acting in the direction of motion.
* Constant Velocity: If the velocity is constant, the power is simply the product of force and velocity. However, if the velocity is changing, you need to use calculus to determine the instantaneous power.
Example:
If a force of 10 Newtons is applied to a body moving at a velocity of 5 meters per second, the power is:
P = F * V = 10 N * 5 m/s = 50 Watts
