You are lying in bed and want to shut your bedroom door

By Allen Kazadi

You are lying in bed and want to shut your bedroom door. You have a bouncy “superball” and a blob of clay, both with the same mass. Part A Which one would be more effective to throw at your door to close it?

Answer:

The ball would be faster. Because the ball would bounce off the door, a greater amount of energy is transfered into the door because the ball needs that energy to bounce back. A clay ball just sticks and keeps the same amount of energy. Trust me on this one I got it wrong many times before
