Power [Force,Velocity]

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:

• (F) Force
• (θ) Angle which the force is applied
• (v) Velocity

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).
