6.8A Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It depends on the height and mass of the object.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

What factors affect potential energy?

Back

Potential energy depends on the height and mass of the object.

Front

At which point does a pendulum have maximum potential energy?

Back

A pendulum has maximum potential energy at its highest point.

Front

At which point does a pendulum have maximum kinetic energy?

Back

A pendulum has maximum kinetic energy at its lowest point.

Front

How is potential energy converted to kinetic energy?

Back

Potential energy is converted to kinetic energy when an object moves from a higher position to a lower position.

Front

What is the formula for kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

The formula for potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Give an example of potential energy.

Back

A book on a shelf has potential energy because of its height above the ground.

Front

Give an example of kinetic energy.

Back

A rolling ball has kinetic energy because it is in motion.
