Concepts/Relationships: Energy Exchanges and Wave Properties

Front

What is the relationship between frequency and wavelength?

Back

Higher Frequency = Shorter Wave.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration.

Front

How is Gravitational Potential Energy calculated?

Back

Gravitational Potential Energy (PE) = mass (m) × gravitational acceleration (g) × height (h).

Front

What is the formula for calculating Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 × mass (m) × velocity (v)².

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

If the period of a wave is 4 seconds, what is the frequency?

Back

Frequency (f) = 1/Period (T) = 1/4 Hz.

Front

What is the definition of frequency in wave properties?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz).

Front

What is the relationship between energy and mass in physics?

Back

According to Einstein's equation E=mc², energy (E) is equal to mass (m) times the speed of light (c) squared.

Front

What happens to the potential energy of an object as it is lifted higher?

Back

The potential energy increases as the height of the object increases.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on position, while kinetic energy is the energy of motion.
