Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object has due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. For example, a ball held at a height has potential energy.

Front

What is the Law of Conservation of Energy?

Back

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

Front

When is Potential Energy transformed into Kinetic Energy?

Back

Potential Energy is transformed into Kinetic Energy when an object at rest is put into motion.

Front

Which has more Potential Energy: a ball on the ground or a ball on a table?

Back

The ball on the table has more Potential Energy because it is at a higher elevation.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy depends on the mass of the object and the speed at which it is moving. The formula is KE = 1/2 mv².

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the potential energy an object has due to its height above the ground. It is calculated as PE = mgh.

Front

How can you increase the Potential Energy of an object?

Back

You can increase the Potential Energy of an object by raising it to a higher position or increasing its mass.

Front

What happens to the Kinetic Energy of a moving object when it slows down?

Back

As a moving object slows down, its Kinetic Energy decreases.

Front

What is an example of energy transformation?

Back

An example of energy transformation is when a roller coaster goes down a hill; its Potential Energy is converted into Kinetic Energy.
