Energy Transformations and Conservation of Energy

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy to electrical energy.

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 is stored in an object due to its position?

Back

Potential energy is the energy stored in an object due to its position or state.

Front

What type of energy is associated with motion?

Back

Kinetic energy is the energy associated with the motion of an object.

Front

Give an example of energy transformation in a flashlight.

Back

In a flashlight, chemical energy from the battery is transformed into electrical energy, which is then transformed into light 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 an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, such as a moving car.

Front

How does a hydroelectric dam generate electricity?

Back

A hydroelectric dam converts the potential energy of stored water into mechanical energy as it falls, which then turns turbines to generate electrical energy.

Front

What is radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, such as light.

What is an example of energy transformation in a candle?

Back

In a candle, chemical energy from the wax is transformed into thermal energy (heat) and radiant energy (light) when it burns.
