What is energy transformation?

Back

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

What type of energy is transformed in a microwave oven?

Back

In a microwave oven, electrical energy is transformed into thermal energy (heat) and light energy.

Front

What energy transformation occurs when a battery powers a flashlight?

Back

The energy transformation is from chemical energy (in the battery) to electrical energy to light energy.

Front

What is the energy transformation in a hydroelectric dam?

Back

The energy transformation is from potential energy (water at height) to kinetic energy (moving water) to electrical energy (generated electricity).

Front

What energy transformation occurs when a lamp is plugged in?

Back

The energy transformation is from electrical energy to light energy.

Front

What happens during energy transformations?

Back

Energy changes from one form to another, but it is not created or destroyed.

Front

What is an example of energy transformation in nature?

Back

Photosynthesis in plants transforms solar energy into chemical energy.

Front

What type of energy is involved in a fire?

Back

A fire transforms chemical energy (from fuel) into thermal energy (heat) and light energy.

Front

What is the difference between potential and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.

Front

What is an example of potential energy?

Back

A rock at the top of a hill has potential energy due to its height.
