Kinetic and Potential Energy Review

Front

What is the definition of potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to its height above the ground.

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

How does potential energy convert to kinetic energy?

Back

Potential energy converts to kinetic energy when an object moves from a higher position to a lower position, such as when it falls.

Front

What happens to kinetic energy as an object slows down?

Back

As an object slows down, its kinetic energy decreases.

Front

Where is potential energy highest in a roller coaster?

Back

Potential energy is highest at the top of a big hill on a roller coaster.

Front

Where is kinetic energy highest in a roller coaster?

Back

Kinetic energy is highest at the lowest point of the roller coaster, where the speed is greatest.

Front

What factors affect the amount of kinetic energy an object has?

Back

The amount of kinetic energy an object has depends on its mass and velocity.

Front

What is the relationship between kinetic and potential energy in a closed system?

Back

In a closed system, the total mechanical energy (kinetic + potential) remains constant, assuming no energy is lost to friction or air resistance.

Front

How does height affect potential energy?

Back

Potential energy increases with height; the higher an object is, the more potential energy it has.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a book on a shelf, which has energy due to its height.
