Harnessing Human Energy Ch. 1

Front

What is kinetic energy?

Back

The energy an object has because it is moving.

Front

What is potential energy?

Back

The energy an object has because of its position or state, such as a wound-up toy or a battery.

Front

Give an example of kinetic energy.

Back

A flying soccer ball.

Front

Give an example of potential energy.

Back

A battery or a wound-up toy.

Front

What happens to energy when an object moves?

Back

Energy is transferred or transformed, allowing the object to move.

Front

What type of energy does a wind-up toy have when it is wound up?

Back

Potential energy, which converts to kinetic energy when released.

Front

What is the relationship between energy and movement?

Back

Whenever something moves or changes, it is because of energy.

Front

What is an example of energy being transformed?

Back

A battery converting chemical energy into electrical energy.

Front

What type of energy does a stationary object have?

Back

Potential energy, as it has the potential to move.

Front

What is the formula for kinetic energy?

Back

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