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 its velocity.

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.

Front

What is the formula for Kinetic Energy?

Back

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

Front

What is the formula for Potential Energy?

Back

The formula for gravitational potential energy (PE) is 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, conserving the total mechanical energy.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving skateboard, a running dog, or a flowing river are all examples of kinetic energy.

Front

What is an example of Potential Energy in everyday life?

Back

A book on a shelf, a stretched rubber band, or water stored in a dam are examples of potential energy.

Front

Where is potential energy highest on a roller coaster?

Back

Potential energy is highest at the top of a big hill on a roller coaster.

Front

Where is kinetic energy highest on a roller coaster?

Back

Kinetic energy is highest at the bottom of a hill on a roller coaster.

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, but the total energy remains constant in a closed system.
