Question

a pile of similar coins is hit very strongly at the bottom of the pile by a striker. What will happen to the (i) lowest coin (ii) rest of the coins? Explain your observation with reason.
​

Answer 1

Answer:

lower coin will move but the rest will be in the same state and comes down this is a example for inertia of rest

Answer 2

If we hit the bottom coin of the pile strongly by the striker then the bottom coin comes into motion (comes out) but the rest of the coins remain in the form of pile due to inertia of rest (inability of the other coins to move from state of rest)
