1. K - Riding a bike involves motion, so it is kinetic energy.<br />2. K - A bird flying is in motion, so kinetic energy.<br />3. P - Batteries store energy for later use, so they have potential energy.<br />4. K - Light is a form of energy in motion, so it is kinetic energy.<br />5. P - A rock sitting at the top of a hill has the potential to fall and convert its potential energy into kinetic energy.<br />6. P - Holding a volleyball in your hand has potential energy due to the position and the force required to hold it.<br />7. P - A bell at the top of a tower has potential energy due to its position and the force required to hang it.<br />8. P - Keys on the hook have potential energy due to their position and the force required to hold them.<br />9. K - A moving car is in motion, so it is kinetic energy.<br />10. K - Football players tackling involve motion, so it is kinetic energy.<br />11. P - A light bulb stores energy in the form of light, so it has potential energy.<br />12. P - A roller coaster at the top of a hill has potential energy due to its position and the force required to keep it there.<br />13. P - An unplugged hair dryer has potential energy stored in its internal components.<br />14. K - Typing on a keyboard involves motion, so it is kinetic energy.<br />15. P - Food has potential energy that can be converted into kinetic energy when it is digested.<br />16. K - A burning log is in motion at the molecular level, so it is kinetic energy.<br />17. K - A flashlight turned on is in motion, so it is kinetic energy.
