Energy

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What are the two main types of energy?

Back

Potential energy and kinetic energy.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

How is energy measured?

Back

Energy is measured in Joules.

Front

What is an example of potential energy?

Back

A car parked on a hill has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

A tennis ball rolling across the court has kinetic energy.

Front

What happens to potential energy as an object falls?

Back

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

Front

What is the formula for kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the relationship between mass and kinetic energy?

Back

Kinetic energy increases with mass; if mass increases, kinetic energy increases.
