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.

What happens to energy when a roller coaster goes from point B to point C?

Back

The roller coaster transforms kinetic energy to potential energy as it climbs to a higher position.

Front

Where is the maximum potential energy on a roller coaster?

Back

At the top of a big hill.

Front

What type of energy does a battery convert?

Back

A battery converts chemical energy into electrical energy.

Front

What type of energy transformation occurs when plants make food using sunlight?

Back

Plants transform radiant energy (sunlight) into chemical energy (food) through photosynthesis.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion.

Front

What is potential energy?

Back

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

Front

Give an example of energy transformation in a light bulb.

Back

A light bulb transforms electrical energy into light energy and thermal energy.

Front

What is mechanical energy?

Back

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

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.
