Potential and Kinetic 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 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

How does energy transform from Potential to Kinetic?

Back

Energy transforms from potential to kinetic when an object moves from a higher position to a lower position, such as a ball rolling down a hill.

Front

What is an example of Kinetic Energy?

Back

A moving skateboard is an example of kinetic energy.

Front

What is an example of Potential Energy?

Back

A book on a shelf has potential energy due to its height above the ground.

Front

What happens to Kinetic Energy when speed increases?

Back

Kinetic energy increases as the speed of an object increases, since it is proportional to the square of the speed.

Front

What happens to Potential Energy when height increases?

Back

Potential energy increases as the height of an object increases, since it is directly proportional to height.

Front

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

Back

In a pendulum, kinetic energy is highest at the lowest point of the swing, while potential energy is highest at the highest points of the swing.
