Potential and Kinetic Energy

Front

What is Kinetic Energy (KE)?

Back

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

Front

What is Potential Energy (PE)?

Back

Potential Energy is the stored energy in an object due to its position or state. It is often associated with height or condition.

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) is 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) is 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 height and Potential Energy?

Back

The higher an object is, the greater its Potential Energy, because it has the potential to fall.

Front

What is an example of Kinetic Energy?

Back

A moving car, a running athlete, or a flowing river are all examples of Kinetic Energy.

Front

What is an example of Potential Energy?

Back

A book on a shelf, a drawn bow, or water stored in a dam are all examples of Potential Energy.

Front

What happens to Kinetic Energy when an object speeds up?

Back

When an object speeds up, its Kinetic Energy increases because it is proportional to the square of its velocity.

Front

What happens to Potential Energy when an object is lifted?

Back

When an object is lifted, its Potential Energy increases because it gains height.
