Question

Why only thecarrom coin at the bottom of a pile of coins is removed when a fast moving carrom coin strikes it?

Answer 1

Answer:This is due to the phenomenon of Inertia.

Explanation:Newton's first law states that," A body at rest or in motion tends to be at rest or motion until acted upon by any other external force." and on the basis of this statement we can theorize that only the carom coin at the lowest part of the pile is moved when hit by the striker as the coins above it experience Inertia and thus tend to stay at their mean position.

Hope this explains it. ;)

Answer 2

Answer:

Explanation:

a) On hitting the carrom coin pile its lower coin will move out only beacuse, all above tends to maintain its state of rest. In simple words inertia of the above coins don't allow them to change their position.

b) On firing a bullet from a gun, the gun moves backward beacuse of the recoil velocity produced by firing the bullet and hence, leads to the shooter to moves back.
