FLASHCARD QUESTION

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance a wave moves from its rest position, representing the height of the wave.

FLASHCARD QUESTION

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = mgh.

3.

FLASHCARD QUESTION

Front

How do you calculate gravitational potential energy?

Back

Gravitational potential energy (PE) is calculated using the formula PE = mgh, where m is mass (kg), g is acceleration due to gravity (9.8 m/s²), and h is height (m).

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

FLASHCARD QUESTION

Front

What is the formula for calculating gravitational potential energy of a 12 kg rock at a height of 25 meters?

Back

PE = mgh = 12 kg * 9.8 m/s² * 25 m = 2940 J.

FLASHCARD QUESTION

Front

What is the significance of the height in gravitational potential energy?

Back

The height of an object in a gravitational field directly affects its gravitational potential energy; the higher the object, the greater the potential energy.
