What is Work, Energy, and Power?
Work, energy, and power are fundamental concepts in physics that describe how forces cause objects to move and how quickly that happens.
Work transfers energy, Energy is the capacity to do work, and Power measures how quickly work is done or energy is transferred.
To calculate acceleration for force problems, use our Kinematics Motion Calculator.
To analyze forces in detail, check out our Forces & Newton's Laws Calculator.

Frequently Asked Questions (FAQ)
Q: What is the relationship between work and energy?
A: Work is the transfer of energy. The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy.
Q: What is the formula for Kinetic Energy?
A: Kinetic Energy (KE) is calculated as KE = ½mv², where m is mass and v is velocity.
Q: What is Power?
A: Power is the rate at which work is done or energy is transferred. It is calculated as P = W/t (Work divided by time).
