Sagot :
Answer:
11. A door accelerating when pushing it.
12. A person sliding along the floor.
13. Water dropping from the faucet.
14. Courtains descending when loosening them.
Explanation:
For kinetic energy, any example that does not move horizontally will do. Something accelerating or decelerating is a good example (Ek=1/2mv^2, where v is velocity).
For potential energy try to think of things moving vertically. Potential energy comes from the height of an object (Ep=mgh, where h is height).
Notice that example 13 and 14 represent potential energy turning into kinetic energy, height becomes lower, so velocity increases.
