Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object that is in motion. The faster an object moves, the more kinetic energy it has.

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state. It has the potential to do work when released.

What happens to Kinetic Energy when an object speeds up?

Back

When an object speeds up, its kinetic energy increases because kinetic energy is proportional to the square of its speed.

What happens to Potential Energy when an object is lifted higher?

Back

When an object is lifted higher, its potential energy increases because it has more stored energy due to its elevated position.

How is Potential Energy calculated?

Back

Potential Energy (PE) is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
