Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Throwing an egg against the wall made it break because the wall applied a larger force over a shorter time.
A
true
B
false
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -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-2: -The egg that hit the crash barrier experienced the greater impact force due to the shorter impact time. The egg that collided with the bed sheet experienced the greater time of impact, thereby experiencing a smaller stopping force over a longer time interval.

Detailed explanation-3: -When an egg is dropped from a higher height, it reaches a greater speed before hitting the ground. So the egg dropped from 5 meters has a greater velocity when it strikes the ground. It thus experiences the greater velocity change during the collision.

Detailed explanation-4: -Reducing the impact speed also reduces the impact force. Distributing the impact force over enclosure also reduces the force exerted on the egg. Since the change in momentum is fixed, impulse can be controlled by increasing the impact time.
