2.)When you had a minimum stretch of the rubber band and released the bullet what happened to the cup being hit?
3.)How about when you stretched it to the maximum strength?
4.)When you hit the cup, did it fall in the same distance?
5.)What made it different?
6.) What type of energy is shown when the bullet fell from a certain height? 7.)What energy transformation took place when the paper bullet was released? 8.)How was work being done when you do the angry paper?

2.A rubber band is an elastic material in nature. When stretched, it changes its shape and when the applied force is removed, it regains its original shape.

3.The best time to stretch is after exercise, when your muscles are warm. it's safer to stretch a warm muscle, and warm muscles are more relaxed and have greater range of motion.

4.If you neglect air resistance, objects falling near Earth's surface fall with the same approximate acceleration 9.8 meters per second squared (9.8 m/s2, or g) due to Earth's gravity.

5.It may be no coincidence

6.Thus, their original potential energy
