Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or height. It is the energy that has the potential to be converted into kinetic energy.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass of the object and the speed at which it is moving.

Front

At which point is Kinetic Energy greatest in a roller coaster?

Back

Kinetic Energy is greatest at the lowest point of the roller coaster, where the speed is highest.

Front

At which point is Potential Energy greatest in a roller coaster?

Back

Potential Energy is greatest at the highest point of the roller coaster, where the height is maximum.

Front

What factors affect Potential Energy?

Back

Potential Energy is affected by the mass of the object and its height above the ground.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and the square of its speed.

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

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 speed.

Front

What is the relationship between Potential and Kinetic Energy?

Back

Potential Energy can be converted into Kinetic Energy and vice versa. For example, when an object falls, its Potential Energy decreases while its Kinetic Energy increases.

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.
