Question

When a fast moving striker strikes a pile of carrom coins only the bottom coin is removed from the pile. Give Scientific Reasons.

Answer 1

Hint: The first law of motion says an object at rest tends to be in rest position until and unless an external force acts upon it. There are 3 types of inertia (i) Inertia of rest (ii) inertia of motion (iii) inertia of rotation. Inertia is the resistance of any physical object to any change in its velocity. This includes changes to the object’s speed, or direction of motion. An aspect of this property is the tendency of objects to keep moving is a straight line at a constant speed, when no forces act upon them.

Complete step by step answer:
Only the coin at the bottom is thrown away; others will remain in the previous stage. This is because of inertia of rest. The upper coin remained at rest with coins at bottom by sudden hit heat (force) by strike move. The principle of inertia is one of the fundamental principles in physics.
If the net external force is zero, a body at rest continues to remain at rest and a body in motion continues to move with a uniform velocity. This property of the body is called inertia (i.e. resistance to change). An object stays where it is placed, and it will stay there until you or something else moves it. That is, dust particles stay at rest until you shake a carpet. An object will continue at the same speed until a force acts on it.

Note:
If the net external force is zero, a body at rest continues to remain at rest and a body in motion continues to move with a uniform velocity. This property of the body is called inertia.
There are these type of inertia
1) Inertia of motion- the ability of the body to resist any change in its state of rest, that is, the body at rest.
2) Inertia of motion- the ability of the body to resist any change in state of motion, that is, moving the body with uniform speed.
3) Inertia of rotation- the ability of a body to resist any change in its state of rotation, that is, a rotating body with uniform speed.
They all comprise the law of inertia. This law was derived by sir Isaac Newton with the help of glass, paper and coin.
