Potential and Kinetic Energy Intro

Front

What is kinetic energy?

Back

Kinetic energy is the energy that an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical energy.

Front

What is the relationship between potential energy and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa. For example, when an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is an example of an object with kinetic energy?

Back

A tennis ball rolling across the court is an example of an object with kinetic energy.

Front

At which point is kinetic energy greatest in a falling object?

Back

Kinetic energy is greatest just before the object hits the ground, as it has converted most of its potential energy into kinetic energy.

Front

Which of the following is not a form of kinetic energy?

Back

Elastic energy is not a form of kinetic energy; it is a form of potential energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its height above the ground, calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What is an example of potential energy?

Back

A drawn bow has potential energy due to the tension in the string.

Front

What is the formula for calculating kinetic energy?

Back

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