FLASHCARD QUESTION

Front

What is gravitational potential energy (GPE)?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically calculated as GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

FLASHCARD QUESTION

Front

What does the Law of Conservation of Energy state?

Back

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

3.

FLASHCARD QUESTION

Front

How is total mechanical energy defined?

Back

Total mechanical energy is the sum of an object's potential energy and kinetic energy. It remains constant in a closed system without external forces.

4.

FLASHCARD QUESTION

Front

At what point does an object have maximum kinetic energy?

Back

An object has maximum kinetic energy at the lowest point of its motion, where its speed is greatest.

5.

FLASHCARD QUESTION

Front

At what point does an object have maximum potential energy?

Back

An object has maximum potential energy at the highest point of its motion, where its height is greatest.

6.

FLASHCARD QUESTION

Front

What is kinetic energy (KE)?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated as KE = 1/2 mv², where m is mass and v is velocity.

7.

FLASHCARD QUESTION

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, keeping the total mechanical energy constant.
