PopFlashcard!-Potential and Kinetic 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 raised object has gravitational potential energy.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the greater its potential energy. This is because potential energy is calculated as mass x gravity x height.

Front

What is the formula for Kinetic Energy?

Back

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

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, assuming no energy is lost to air resistance.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a running dog, or a flowing river are all examples of kinetic energy.

Front

What is an example of Potential Energy in everyday life?

Back

A stretched rubber band, a book on a shelf, or water stored in a dam are all examples of potential energy.

Front

At which point is Potential Energy greatest on a ramp?

Back

Potential energy is greatest at the highest point of the ramp.

Front

What type of energy does a skateboard have when it is rolling down a hill?

Back

The skateboard has kinetic energy as it is in motion.

Front

What type of energy does a bobsled have at the top of a hill?

Back

The bobsled has potential energy at the top of the hill due to its height.
