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

What is the formula for calculating Kinetic Energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What factors affect Kinetic Energy?

Back

Kinetic energy is affected by two main factors: mass and speed of the object.

Front

What happens to Potential Energy when an object is lifted?

Back

When an object is lifted, its potential energy increases because it is moved to a higher position against the force of gravity.

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 Kinetic Energy in everyday life.

Back

A moving car, a flowing river, or a person running are all examples of kinetic energy.

Front

Give an example of Potential Energy in everyday life.

Back

A book on a shelf, a drawn bow, or water stored in a dam are examples of potential energy.

Front

How does mass affect Kinetic Energy?

Back

The greater the mass of an object, the more kinetic energy it has at a given speed.

Front

How does speed affect Kinetic Energy?

Back

The kinetic energy of an object increases with the square of its speed; if speed doubles, kinetic energy increases by four times.
