Question

'a glass tumbler breaks on a hard floor while it does not break on sand, when it falls from a height''. give reasons.

Answer 1

sand absorbs the energy particularly the kinetic energy of motion whereas hard floor is not able to absorb the energy so the energy is then transferred to the glass, making the bonds of the glass break.

Answer 2

Yes, it is observed that a glass tumbler breaks when it falls on the hard floor, but it does not break when it falls on the sand.

This happens because the sand is known to be less dense as compared to that of floor.

Being the floor denser it cause glass vessel to break.
