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, typically related to its height above the ground.

2.

FLASHCARD QUESTION

Front

At which point does a ball have the greatest gravitational potential energy?

Back

The ball has the greatest gravitational potential energy at its highest point because it has the maximum height and will convert this energy to kinetic energy as it falls.

3.

FLASHCARD QUESTION

Front

What happens to potential energy as an object falls?

Back

As an object falls, its gravitational potential energy decreases while its kinetic energy increases, assuming energy is conserved.

4.

FLASHCARD QUESTION

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, which depends on its mass and speed.

5.

FLASHCARD QUESTION

Front

How is kinetic energy calculated?

Back

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

6.

FLASHCARD QUESTION

Front

What is the relationship between speed and kinetic energy?

Back

The kinetic energy of an object increases as its speed increases, since kinetic energy is proportional to the square of the speed.

7.

FLASHCARD QUESTION

Front

What is energy conservation?

Back

Energy conservation is the principle that energy cannot be created or destroyed, only transformed from one form to another.
