physics: you can't throw a raw egg against the cement sidewalk w/o braeking it...?
but you can throw it at the same speed into springy grass without breaking it. Explain why

The cement does not absorb the kinetic energy, so when the egg hits the cement all of its energy of motion remains in the egg itself - it slows down instantly and its shell is not strong enough to dissipate the energy without breaking.
The grass is flexible and resilient, and each blade will absorb a small amount of the kinetic energy of the egg, slowing it down more gradually.

one of them is elastic and the other is inelastic. The grass 'deforms' to cushion the egg, while the wall doesn't.
