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 square of 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 energy.

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

What happens to Kinetic Energy when speed increases?

Back

As speed increases, Kinetic Energy increases. Specifically, it increases with the square of the speed.

Front

What is an example of Potential Energy?

Back

A rock held at a height has Potential Energy due to its position above the ground.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic Potential Energy.

Front

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

Back

In a pendulum, energy continuously transforms between Kinetic Energy (when moving) and Potential Energy (at the highest points).

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What type of energy does food provide?

Back

Food provides Potential Energy, which is converted into Kinetic Energy when consumed and used by the body.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the Potential Energy an object has due to its height above the ground, calculated as PE = mgh.
