Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its speed.

Front

What is the relationship between height and potential energy?

Back

The higher an object is positioned, the more potential energy it has.

Front

What is the relationship between speed and kinetic energy?

Back

The faster an object moves, the more kinetic energy it possesses.

Front

Give an example of potential energy.

Back

A book on a shelf has potential energy due to its height.

Front

Give an example of kinetic energy.

Back

A rolling ball has kinetic energy due to its motion.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

Potential energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How can potential energy be converted to kinetic energy?

Back

When an object is released from a height, its potential energy converts to kinetic energy as it falls.
