Ok . So i know its already explained but can any1 explain a bit more[Both of them]. Write Heading 'Activity 9.1' [then explain]then heading 'Activity 9.2 [then explain] So that i know which explanation is for which activity. Plsssss Help!

Answer:
Activity 9.1
Explanation:
A moving body wants to remain in the state of motion while a resting body tends to remain in a steady position only. This physicist call “law of inertia” or Newton’s first law of motion.
When an external force enough to break the inertia comes and applies to the body then only the body changes its state of motion.
Here the striker hits the bottom coin and breaks the inertia of the bottom coin.
The bottom coin applies a frictional for on the rest of the pile of the coins. But this force is not enough to break the inertia of the other coins. As a result, the remaining coins fall back to the bottom of the carrom board.
Activity 9.2
Explanation:
This activity is similar to activity 9.1 also. There we struck the pile of coins using the striker.
Here the coin is at the rest also wants to remain at the rest: Newton’s first law of motion. When we hit the card fast, the energy of the card does not transfer to the coin. As a result, the coin does not move and falls inside the glass due to gravity.
