PE and KE

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 stored energy based on an object's position or state. It can be gravitational, elastic, or chemical.

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, where the speed is highest.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy depends on mass and speed. Increasing either mass or speed increases the kinetic energy.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What type of energy is associated with a stretched spring?

Back

The energy associated with a stretched spring is called Elastic Potential Energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object possesses due to its height above the ground, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only change forms.

Front

What is the relationship between mass and speed in Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed; if speed doubles, kinetic energy increases by a factor of four.

Front

What is an example of Chemical Energy?

Back

Chemical Energy is stored in the bonds of chemical compounds, such as in food or batteries.
