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. For gravitational potential energy, it is 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. This is because potential energy is directly proportional to height.

What is the relationship between Kinetic and Potential Energy in a roller coaster?

Back

As a roller coaster car moves up, it gains potential energy and loses kinetic energy. As it descends, potential energy is converted back into kinetic energy.

Front

What happens to Kinetic Energy when speed increases?

Back

Kinetic Energy increases with the square of the speed. If the speed doubles, the kinetic energy increases by a factor of four.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for Kinetic Energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

The formula for Potential Energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How can you increase the Kinetic Energy of an object?

Back

You can increase the Kinetic Energy of an object by increasing its mass or its speed.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its position in a gravitational field, typically related to its height above the ground.

Front

What is the effect of mass on Potential Energy?

Back

Potential Energy increases with an increase in mass. The more massive an object, the more potential energy it has at a given height.
