Kinetic & 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

What factors affect Kinetic Energy?

Back

Kinetic energy depends on two factors: speed and mass of the object.

Front

How is Potential Energy calculated?

Back

Potential energy 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 happens to Potential Energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

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

Back

In a roller coaster, potential energy is highest at the top of the hills, and kinetic energy is highest at the lowest points.

Front

What is Mechanical Energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object.

Front

Can an object have both Kinetic and Potential Energy?

Back

Yes, an object can have both kinetic and potential energy at the same time, such as a ball thrown into the air.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is an example of Kinetic Energy in everyday life?

Back

An example of kinetic energy is a moving car or a person running.
