Front

What is the difference between kinetic energy and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is the energy stored due to an object's position.

Front

What is energy?

Back

The ability to do work or cause change.

Front

What is work in physics?

Back

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

Front

What is the formula for calculating work?

Back

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 done on an object results in a change in its energy.

Front

What is mechanical energy?

Back

The sum of potential energy and kinetic energy in an object.
