The Power from Force and Velocity calculator uses the formula, P = F⋅cos(θ)⋅v, to compute power as a function of Force (F), the angle by which the force is applied (θ), and velocity (v).
INSTRUCTION: Choose units and enter the following:
Power (P): The calculator returns the power (P) in watts. However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formula for power derived from a force applied at an angle at a velocity is:
`P = F*cos(theta) * v`
where:
- P = Power from force and velocity
- F = Applied Force
- θ = Angle that the force is applied
- v = Velocity
Power is the amount of energy consumed or produced over time.
- Power is a measurement of the energy used to move vehicles (automobiles, trucks, tractors, trains, boats and airplanes).
- Power is the measurement of energy consumed by a motor and transferred to the drive or wheels.
- Power is the amount of electrical energy consumed or produced by a system over time such as the energy produced by a hydroelectric dam or energy consumed by an electrical motor.
Power Units
Power is most commonly measured in watts (W). One watt is equal to one joule per second (1 W = 1 J / 1 s). Power is also measured in horsepower (hp) where 1 horsepower equals 745.7 watts. Power is also measured in heat energy transfer as BTUs per hour (BTU/h).
