Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

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

Front

What is Potential Energy?

Back

Potential Energy is the stored energy of an object due to its position or state. It has the potential to be converted into kinetic energy.

What happens to the potential energy of a ball as it rolls down a hill?

Back

As the ball rolls down the hill, its potential energy decreases while its kinetic energy increases.

Front

Give an example of an object with Potential Energy.

Back

An apple hanging from a tree has potential energy because of its height above the ground.

Front

Give an example of an object with Kinetic Energy.

Back

A car driving down the road has kinetic energy because it is in motion.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has due to the gravitational force acting on it.

Front

What is the relationship between Kinetic Energy and speed?

Back

Kinetic Energy increases with the square of the speed. If the speed doubles, the kinetic energy increases by four times.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground and the force of gravity acting on it.

Front

What happens to the energy of a roller coaster at the top of a hill?

Back

At the top of a hill, the roller coaster has maximum potential energy and minimum kinetic energy.

Front

What happens to the energy of a roller coaster as it descends?

Back

As the roller coaster descends, potential energy is converted into kinetic energy, increasing its speed.
