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 square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It is often associated with gravitational energy when an object is elevated.

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 if the speed of an object doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.

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

Give an example of an object with Potential Energy.

Back

A book placed on a shelf has Potential Energy due to its height above the ground.

Front

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

Back

In a pendulum, energy continuously transforms between Kinetic Energy (when it is moving) and Potential Energy (at the highest points of its swing).

Front

What factors affect Potential Energy?

Back

Potential Energy is affected by the object's mass, the height above the ground, and the gravitational force acting on it.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a flowing river, or a person running are all examples of Kinetic Energy in action.
