Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It has the potential to do work when released.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of motion. It is the energy an object possesses due to its movement.

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.

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.

Front

What is the formula for calculating Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

How does height affect Potential Energy?

Back

As height increases, Potential Energy increases because it is directly proportional to height.

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed; if speed doubles, Kinetic Energy increases by four times.

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 Potential and Kinetic Energy in a closed system?

Back

In a closed system, the total energy (Potential + Kinetic) remains constant, demonstrating the conservation of energy.
