Work, Power, and Energy Concepts

Front

What is Work?

Back

Work is done when a force causes an object to move in the direction of the force.

Front

What is Power?

Back

Power is the rate at which work is done or energy is transferred over time.

Front

What is Energy?

Back

Energy is the ability to do work or cause change.

Front

How is Work calculated?

Back

Work is calculated using the formula: Work = Force x Distance x cos(θ), where θ is the angle between the force and the direction of motion.

Front

What is the relationship between Work and Energy?

Back

Work is a transfer of energy; when work is done on an object, energy is transferred to that object.

Front

What are the units of Work, Power, and Energy?

Back

Work and energy are measured in Joules (J), while power is measured in Watts (W).

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object due to its motion, calculated as KE = 1/2 mv².

Front

What is Potential Energy?

Back

Potential energy is the stored energy of an object due to its position or state, calculated as PE = mgh.
