Potential and Kinetic Energy

Front

What is the definition of Kinetic Energy?

Back

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

What is the definition of Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration. It is often associated with gravitational energy, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

How does the height of an object affect its Potential Energy?

Back

The Potential Energy of an object increases with height, as it is directly proportional to the height (PE = mgh).

Front

What happens to the Kinetic Energy of an object as it slows down?

Back

As an object slows down, its Kinetic Energy decreases because it is dependent on the square of its velocity.

Can an object have both Kinetic and Potential Energy at the same time?

Back

Yes, an object can have both Kinetic and Potential Energy simultaneously, such as a roller coaster at the top of a hill that is about to descend.

What is an example of Kinetic Energy in everyday life?

Back

An example of Kinetic Energy in everyday life is a car driving down the road.

How is energy conserved in a closed system involving Kinetic and Potential Energy?

Back

In a closed system, the total mechanical energy (sum of Kinetic and Potential Energy) remains constant, as energy can transform from one form to another but is not lost.
