Energy and Wave Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object that is moving or has the ability to move.

Front

True or False: Insulation can keep a house cool on a hot day.

Back

True

Front

What does the gravitational potential energy of an object depend on?

Back

The gravitational potential energy of an object depends on its height above Earth and its weight.

Front

What are the parts of a longitudinal wave where particles of matter are spread farthest apart called?

Back

These parts are called rarefactions.

Front

What happens when you change the frequency of sound waves?

Back

Changing the frequency of sound waves changes the pitch of sound.

Front

Define potential energy.

Back

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

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the difference between amplitude and wavelength in waves?

Back

Amplitude is the height of the wave from the rest position, while wavelength is the distance between two consecutive crests or troughs.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to temperature.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
