Why do we call Newton’s First Law of Motion as Law of Inertia? and Give two examples of Inertia.
Law of Inertia
First Law of motion is also sometimes called the “Law of Inertia” due to reason given below’. The inability of matter to change its state of rest or of uniform motion is called Inertia. First Law of motion which is mainly concerned with this property is also called the “Law of Inertia”.
Examples of Inertia
1) Cover a glass with a post card and place a coin on it. Now strike tile Post card swiftly with the nail of your finger. If the stroke has been made correctly the post card will be thrown away and the coin will stop in the glass.
2) If a moving bus stops suddenly, the passenger standing in it feels a jerk in the forward direction and as a result he may fall. It is due to the fact that the lower part of the standing passenger comes to rest as the bus stops. But the upper portion remains in motion due to inertia.
