Energy Forms

Front

What is energy?

Back

Energy is the ability to do work.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work, such as a stretched bow and arrow.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which depends on the speed and mass of an object.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.

Front

What is an example of potential energy?

Back

A stretched bow and arrow is an example of potential energy.

Front

What is an example of kinetic energy?

Back

A moving car is an example of kinetic energy.

Front

How does friction produce thermal energy?

Back

When two surfaces rub against each other, the friction generates heat, producing thermal energy.

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 mass and kinetic energy?

Back

Kinetic energy increases with greater mass and speed.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object.
