Lesson 2: Potential Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It is often associated with the height of an object above the ground.

Front

What is the synonym for potential energy?

Back

Stored energy.

Front

What type of potential energy is associated with an object's height above the ground?

Back

Gravitational potential energy.

Front

Which object has the least gravitational potential energy?

Back

A ball sitting on the ground.

Front

How can you increase gravitational potential energy without changing mass or gravity?

Back

By raising the object farther off the ground.

Front

What is gravitational potential energy dependent on?

Back

It depends on the object's mass, the height above the ground, and the acceleration due to gravity.

Front

What happens to potential energy when an object is lifted higher?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion, which an object possesses due to its movement.

Front

How is potential energy converted to kinetic energy?

Back

When an object falls or moves from a higher position to a lower position, its potential energy is converted into kinetic energy.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in objects that can be stretched or compressed, such as springs or rubber bands.
