Questions About Inertia and Breaking Eggs

hey all
i have some doubts
1. does inertia depend on body's speed
2. why is it difficult to break an egg when it is hold in a specific position

1.No,IIRC,a body's inertia depends only on his mass.
2.Because the forces acting upon its surface distribut in such way,as there's not resulting force directly perpendicular on the surface.If there was such a force,the egg would brake.

1. Yes, inertia does depend on the body's speed. Inertia is the tendency of an object to resist changes in its state of motion. The greater the speed of an object, the greater its inertia and the more force is needed to change its motion. This is why it is more difficult to stop a fast-moving object compared to a slow-moving one.

2. It is difficult to break an egg when it is held in a specific position because of its inertia. When an object is at rest, it tends to stay at rest unless acted upon by an external force. In this case, the egg is at rest and the force needed to break it is not being applied. Additionally, the shape and structure of an egg make it more resistant to breaking, as its curved surface distributes the force applied to it. This is why it is easier to break an egg when it is dropped or thrown, as the force of impact is greater and more evenly distributed.
