Why does a car have less kinetic energy after crashing into a wall?

Back

The energy has been converted into heat and sound.

Front

The potential energy in this image is due to:

• the magnetic attraction between balloon and paper
• the difference in position between the gravity and the paper
• opposite charges on the balloon and paper
• the chemical bonds between the paper and balloon

Back

opposite charges on the balloon and paper
