kinetic and potential energy

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state.

Front

How is potential energy calculated?

Back

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

Front

What is an example of kinetic energy?

Back

A roller coaster speeding down a hill is an example of kinetic energy.

Front

What is an example of potential energy?

Back

The pulled back string on an archer's bow is an example of potential energy.

Front

At which point is potential energy greatest in a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

What happens to potential energy as an object falls?

Back

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

Front

What is the relationship between kinetic and potential energy?

Back

Kinetic and potential energy can convert into each other; as potential energy decreases, kinetic energy increases, and vice versa.

Front

How can you increase potential energy?

Back

You can increase potential energy by raising the height of an object.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).
