Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical energy.

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

How is Potential Energy calculated?

Back

Potential Energy (PE) is calculated using the formula: PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What happens to Kinetic Energy as speed increases?

Back

As speed increases, Kinetic Energy increases. It is proportional to the square of the speed.

Front

What happens to Potential Energy as height increases?

Back

As height increases, Potential Energy increases because it is directly proportional to height.

Front

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

Back

In a pendulum, Kinetic Energy is highest at the lowest point of the swing, while Potential Energy is highest at the highest points of the swing.

Front

What is an example of an object with high Potential Energy?

Back

A book placed on a high shelf has high Potential Energy due to its elevated position.

Front

What is an example of an object with high Kinetic Energy?

Back

A speeding car has high Kinetic Energy due to its mass and high speed.

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.
