Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is 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 (due to height) or elastic (due to deformation).

Front

What is Gravitational Potential Energy (GPE)?

Back

Gravitational Potential Energy is the energy an object possesses because of its height above the ground. It is calculated using the formula GPE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

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. It is commonly seen in springs and bows.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for calculating Kinetic Energy is KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What is the formula for calculating Gravitational Potential Energy?

Back

The formula for calculating Gravitational Potential Energy is GPE = mgh, where m is mass, g is the acceleration due to gravity (approximately 9.8 m/s²), and h is height.

Front

What is an example of an object with Kinetic Energy?

Back

A tennis ball rolling across the court is an example of an object with Kinetic Energy.

Front

What happens to the Kinetic Energy of an object if its speed doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.

Front

What type of energy do plants convert sunlight into during photosynthesis?

Back

Plants convert sunlight into Chemical Energy during photosynthesis.

Front

What is the relationship between Kinetic Energy and mass?

Back

Kinetic Energy is directly proportional to the mass of the object; as mass increases, Kinetic Energy increases if velocity remains constant.
