kinetic and potential energy

Front

What is kinetic energy?

Back

The energy that an object has due to its motion.

Front

What is potential energy?

Back

The stored energy of an object due to its position or condition.

Front

When does an object have the most potential energy?

Back

When it is at its highest point.

Front

What happens to potential energy as an object falls?

Back

It decreases as kinetic energy increases.

Front

What is the formula for kinetic energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for potential energy?

Back

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

Front

Can an object have both kinetic and potential energy at the same time?

Back

Yes, for example, a person climbing a ladder has both types of energy.

Front

What is an example of potential energy?

Back

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

Front

What is an example of kinetic energy?

Back

A rolling ball has kinetic energy due to its motion.

Front

What happens to energy in a closed system?

Back

Energy is conserved; it can change forms but cannot be created or destroyed.
