Energy & Waves (6.8 A&C)

Front

What is the distance between crests of an electromagnetic wave called?

Back

Wavelength

Front

How can you increase the gravitational potential energy of an object without changing its mass and gravity?

Back

Raise the object farther off the ground.

Front

What happens to the potential energy of an object when it is lifted above a person's head?

Back

The object's potential energy will be greater.

Front

In a wave diagram, which number typically represents the crest?

Back

4

Front

What is the energy an object has due to its motion called?

Back

Kinetic energy.

Front

What is the formula for gravitational potential energy?

Back

Potential Energy (PE) = mass (m) × gravity (g) × height (h).

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength is inversely proportional to frequency; as wavelength increases, frequency decreases.

Front

What type of energy is stored in an object due to its position?

Back

Potential energy.

Front

What is the unit of measurement for energy in the International System of Units (SI)?

Back

Joule (J).

Front

What is the principle of conservation of energy?

Back

Energy cannot be created or destroyed, only transformed from one form to another.
