Science Explanation

The technique with the cloth is similar to playing catch with bare hands. As you catch the ball, you can move your hands with the ball as you receive it to spread out the impact time and lessen the sting of the catch. The longer the stopping time, the smaller the resulting force. Likewise, the sheet slows down the moving egg in a way that protects it from breaking.

A suspended cloth sheet with a pocket formed at the bottom will safely catch a tossed egg.

This slowing technique is the opposite of batting a ball. When a bat connects with a ball, the ball experiences a large force. As home run hitters know, one secret of success is a fast swing.

According to Newton’s second law of motion, the force needed to stop a moving object directly depends on how quickly the object is stopped. If an object strikes a hard surface, it may stop instantly and experience an enormous force. If the object can be decelerated more slowly, however, the force needed to stop it is greatly reduced.

Automobiles are designed with Newton’s second law of motion in view. The bumpers are designed to give in a collision, lengthening the impact time and also absorbing the blow. A car’s steering wheel and dashboard are also padded to lengthen impact time and thus soften bumps to the head. In an emergency, an airbag likewise protects a person during sudden deceleration.

Isaac Newton studied motion three centuries ago. He probably would have preferred that his conclusions be called God’s laws rather than Newton’s laws. He strongly believed that the Creator had established the rules of the physical world.
