FLASHCARD QUESTION

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of potential energy and kinetic energy in a system.

2.

FLASHCARD QUESTION

Front

Define Gravitational Potential Energy (GPE).

Back

Gravitational Potential Energy (GPE) is the energy an object possesses due to its position in a gravitational field, calculated as GPE = mgh (mass x gravity x height).

3.

FLASHCARD QUESTION

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy (KE) is the energy an object has due to its motion, calculated as KE = 1/2 mv² (1/2 x mass x velocity squared).

4.

FLASHCARD QUESTION

Front

At what point is GPE maximum in a free-falling object?

Back

GPE is maximum at the highest point of the object's path.

5.

FLASHCARD QUESTION

Front

At what point is KE maximum in a free-falling object?

Back

KE is maximum just before the object hits the ground.

6.

FLASHCARD QUESTION

Front

What happens to GPE as an object falls?

Back

As an object falls, its GPE decreases while its KE increases.

7.

FLASHCARD QUESTION

Front

What is the principle of conservation of mechanical energy?

Back

The principle states that in a closed system, the total mechanical energy (GPE + KE) remains constant if only conservative forces are acting.
