WHICH 2 EXAMPLE IS THE BEST EXAMPLE OF KINETIC ENERGY?
ANSWER
1. SHOOTING A RUBBER BAND.
2.WATER FALLING OVER THE FALL.
Answers
Answer:
If you've ever been shot with a rubber band then you know it has energy in it—enough energy to smack you in the arm and cause a sting! But have you ever wondered what the relationship is between a stretched rubber band at rest and the energy it holds? The energy the rubber band has stored is related to the distance the rubber band will fly after being released. So can you guess one way to test how much energy a stretched rubber band contains?
Background
No mechanical contraption would be any fun if it did not work. But "work," in the physics sense, takes energy. Consider a rope and pulley that bring a bucket up a well. The energy that makes this mechanical system work is provided by a person who pulls up the rope.
