Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be converted into kinetic energy.

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

Front

At which point in a pendulum's swing is Kinetic Energy highest?

Back

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

Front

At which point in a pendulum's swing is Potential Energy highest?

Back

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

Front

What is an example of Kinetic Energy?

Back

A moving car is an example of kinetic energy.

Front

What is an example of Potential Energy?

Back

A drawn bowstring is an example of potential energy.

Front

How does energy transform in a roller coaster?

Back

As a roller coaster climbs, potential energy increases; as it descends, potential energy converts to kinetic energy.

Front

What happens to Kinetic Energy when speed doubles?

Back

If speed doubles, kinetic energy increases by a factor of four, since KE is proportional to the square of the speed.
