Potential and Kinetic Energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the greater its kinetic energy.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, an object at a height has gravitational potential energy.

Front

How does height affect potential energy?

Back

An object's potential energy increases with height. The higher the object, the more potential energy it has.

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on the mass of the object and the speed at which it is moving. The formula is KE = 1/2 mv².

Front

At which point in a pendulum's swing is potential energy the greatest?

Back

Potential energy is greatest at the highest points of the swing.

Front

At which point in a pendulum's swing is kinetic energy the greatest?

Back

Kinetic energy is greatest at the lowest point of the swing.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases.

Front

What is the relationship between potential energy and mass?

Back

Potential energy increases with mass. Heavier objects have more potential energy at the same height.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car, a running dog, or a thrown baseball are all examples of kinetic energy.

What is an example of potential energy in everyday life?

Back

A book on a shelf, water stored in a dam, or a drawn bow are examples of potential energy.
