Topic 3 Waves & Energy Conservation

Front

What is the law of conservation of energy?

Back

A law of physics that states that energy cannot be created or destroyed but can be transferred or transformed from one form to another.

Front

What is a transverse wave?

Back

A wave in which energy is transferred perpendicular to the direction of the wave.

Front

What is a medium in the context of waves?

Back

The material through which a wave travels (e.g., water, air).

Front

What type of wave is a sound wave?

Back

Longitudinal wave.

Front

How can you identify a transverse wave?

Back

In a transverse wave, the particle motion is perpendicular to the energy motion.

Front

What is a longitudinal wave?

Back

A wave in which energy is transferred in the same direction as the wave.

Front

Give an example of a transverse wave.

Back

Light waves are an example of transverse waves.

Front

What is the difference between a transverse wave and a longitudinal wave?

Back

In transverse waves, particle motion is perpendicular to wave motion; in longitudinal waves, particle motion is parallel to wave motion.

Front

What happens to energy in a closed system according to the law of conservation of energy?

Back

Energy can change forms but the total amount of energy remains constant.

Front

What is an example of energy transformation?

Back

When a battery converts chemical energy into electrical energy.
