Energy, Transformations 23

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is the energy an object has because of its height above the ground.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

How does energy transform when an apple falls from a tree?

Back

As the apple falls, its potential energy decreases while its kinetic energy increases.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What type of energy transformation occurs in a battery-powered flashlight?

Back

The energy transformation in a battery-powered flashlight is from chemical energy to electrical energy to light energy.

Front

What happens to potential energy as a boulder rolls down a hill?

Back

As the boulder rolls down the hill, its potential energy decreases and its kinetic energy increases.

Front

At what point does an object have the most gravitational potential energy?

Back

An object has the most gravitational potential energy at its highest point.

Front

What energy transformation occurs when an oven is turned on?

Back

The energy transformation that occurs when an oven is turned on is from electrical energy to thermal energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy held by an object because of its height in a gravitational field.

Front

What is an example of energy transformation in a candle?

Back

In a candle, chemical energy is transformed into thermal energy and then into light energy when it burns.
