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 is often associated with the height of an object above the ground.

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 Kinetic Energy when speed increases?

Back

Increasing an object's speed will increase its Kinetic Energy.

Front

At what point is Kinetic Energy highest in a roller coaster?

Back

Kinetic Energy is highest at the lowest point of the roller coaster.

Front

At what point is Potential Energy highest in a roller coaster?

Back

Potential Energy is highest at the highest point of the roller coaster.

Front

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

Back

As a roller coaster moves up, Potential Energy increases and Kinetic Energy decreases. As it moves down, Kinetic Energy increases and Potential Energy decreases.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

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.
