Detailed explanation-1: -A high impulse is required for breakdown of eggshell. This happens when force acts upon it for a very short period. When the egg is thrown against the wall then its impulse force acts against the egg that causes it to shatter.
Detailed explanation-2: -It won’t break because the sheet slows the movement of the egg as it comes to a stop. The law of motion says that the faster you change the speed of an object, the greater the force applied to the object will be.
Detailed explanation-3: -Usually, it takes a little more than 5 ½ pounds of force to crack an eggshell-much less than the weight of a human being-but the precise amount of force needed depends on the direction in which that force is applied and how much the force is distributed (or not) over the surface of the shell.
Detailed explanation-4: -Gravity causes an object to fall to Earth when dropped. Drop an egg from eye level so that it breaks. When the egg hits the ground with a given force, the ground exerts the same force back on the egg.
