What is energy?

Back

Energy is the ability to do work or cause change. It can exist in various forms, such as kinetic, potential, thermal, and sound energy.

What happens when a guitar string is plucked?

Back

The vibrating string transfers energy to the air, creating sound waves that we hear as music.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is a sound wave?

Back

A sound wave is a type of wave that travels through air (or other mediums) and is created by vibrating objects.

Front

What is wave amplitude?

Back

Wave amplitude is the maximum distance that points on a wave move from their rest position. It is related to the energy of the wave.

Front

What is the relationship between energy and temperature?

Back

When energy is added to a substance, its temperature usually increases, as the particles move faster.

Front

What is an example of energy transfer?

Back

When a rock is dropped into water, some of the energy from the rock is transferred to the water, causing it to splash.

Front

What is the role of vibrations in sound production?

Back

Vibrations create sound waves by transferring energy to the surrounding air, which we perceive as sound.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.

Front

How does sound travel through different mediums?

Back

Sound travels through solids, liquids, and gases by causing particles in the medium to vibrate and transfer energy.
