Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy 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.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object as a result of its height above the ground, calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the greater its potential energy due to the increased gravitational force acting on it.

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and Potential Energy are forms of mechanical energy. As potential energy decreases (e.g., an object falls), kinetic energy increases, and vice versa.

Front

What happens to the Potential Energy of a book when it is moved to a lower shelf?

Back

The potential energy of the book decreases as it is moved to a lower shelf.

Front

Which of the following is NOT an example of Potential Energy? A ball traveling at 10 m/s, a compressed spring, water stored at a dam, a stretched rubber band.

Back

A ball traveling at 10 m/s is NOT an example of Potential Energy; it is an example of Kinetic Energy.

Front

Which object has the most Potential Energy? A ball resting on the ground, a ball being thrown at 100 mph, a ball on top of a refrigerator, a ball resting on the edge of a cliff.

Back

A ball resting on the edge of a cliff has the most Potential Energy.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for calculating Kinetic Energy is KE = 1/2 mv².

Front

What is an example of Kinetic Energy?

Back

An example of Kinetic Energy is a car driving down a hill.
