Extra Credit Kinetic and Potential Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, a stretched rubber band has potential energy.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the more potential energy it has. For example, a rock at the top of a hill has more potential energy than a rock at the bottom.

Front

What happens to Kinetic Energy as speed increases?

Back

As the speed of an object increases, its kinetic energy increases. Kinetic energy is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

At what point does an object have maximum Potential Energy on a roller coaster?

Back

An object has maximum potential energy at the highest point of the roller coaster.

Front

At what point does an object have maximum Kinetic Energy on a roller coaster?

Back

An object has maximum kinetic energy at the lowest point of the roller coaster.

Front

What is the relationship between Potential Energy and Kinetic Energy?

Back

Potential Energy can be converted into Kinetic Energy and vice versa. For example, when a roller coaster descends, its potential energy converts to kinetic energy.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a running dog, or a thrown ball are all examples of kinetic energy.

Front

What is an example of Potential Energy in everyday life?

Back

A book on a shelf, a drawn bow, or a compressed spring are all examples of potential energy.

Front

How does mass affect Kinetic Energy?

Back

The greater the mass of an object, the more kinetic energy it has when moving at the same speed. Kinetic energy is directly proportional to mass.
