Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the edge of a cliff has potential energy.

Front

At which point is potential energy greatest in a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between kinetic energy and speed?

Back

The kinetic energy of an object increases with the square of its speed. If the speed doubles, the kinetic energy increases by four times.

Front

Can an object have both kinetic and potential energy?

Back

Yes, an object can have both kinetic and potential energy at the same time, such as a moving ball at a height.

Front

What is an example of potential energy in everyday life?

Back

A stretched rubber band has potential energy due to its position.

Front

What is an example of kinetic energy in everyday life?

Back

A running dog has kinetic energy due to its motion.

Front

How does height affect potential energy?

Back

The higher an object is positioned, the more potential energy it has due to gravity.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.
