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 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.

Front

What happens to Kinetic Energy when an object speeds up?

Back

Kinetic Energy increases as the speed of the object increases.

Front

What happens to Potential Energy as an object falls?

Back

Potential Energy decreases as the object falls, while Kinetic Energy increases.

Front

What is the formula for Kinetic Energy?

Back

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

Front

What is the formula for Potential Energy?

Back

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

Front

How does a pendulum demonstrate Kinetic and Potential Energy?

Back

At the highest points of the swing, the pendulum has maximum Potential Energy and minimum Kinetic Energy. At the lowest point, it has maximum Kinetic Energy and minimum Potential Energy.

Front

What is Elastic Potential Energy?

Back

Elastic Potential Energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

How does energy transform in a roller coaster?

Back

As a roller coaster climbs, it gains Potential Energy. As it descends, that Potential Energy is converted into Kinetic Energy.

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 Law of Conservation of Energy.
