Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

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 unit is used to measure energy?

Back

The unit used to measure energy is the Joule (J).

Front

What happens to Potential Energy when an object is lifted higher?

Back

The Potential Energy increases as the height of the object increases.

Front

What is the relationship between speed and Kinetic Energy?

Back

Kinetic Energy is directly related to the square of the speed of an object; as speed increases, Kinetic Energy increases.

Front

What is Photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What type of energy is converted during Photosynthesis?

Back

Light energy is converted to chemical energy during Photosynthesis.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object has due to its height above the ground.

Front

What happens to Kinetic Energy when an object slows down?

Back

Kinetic Energy decreases as the speed of the object decreases.

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 speed.
