8th FLASHCARD - 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 of an object based on its position or state. It can be gravitational, elastic, or chemical.

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 height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has, because it has the potential to fall and do work.

Front

What happens to Kinetic Energy as an object slows down?

Back

As an object slows down, its Kinetic Energy decreases because it is losing speed.

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 unit of energy?

Back

Energy is measured in Joules (J).

Front

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

Back

In a pendulum, as it swings, Kinetic Energy and Potential Energy convert into each other; at the highest point, Potential Energy is maximum, and Kinetic Energy is minimum.

Front

What is an example of Potential Energy?

Back

A book on a shelf has Potential Energy due to its height above the ground.
