Potential and Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object due to its motion. It depends on the speed and mass of the object.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object based on its position or height relative to a reference point.

Front

How is Kinetic Energy calculated?

Back

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

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and the square of its speed.

Front

What factors affect Potential Energy?

Back

Potential Energy is affected by the mass of the object, the height above the ground, and the gravitational force.

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and Potential Energy are forms of mechanical energy. They can convert into each other; for example, when an object falls, its Potential Energy decreases while its Kinetic Energy increases.

Give an example of Kinetic Energy in everyday life.

Back

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

Back

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

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases.
