Question

explain why Newton’s first law is called the law of inertia

Answer 1

Answer :

According to the Newton's first law of motion - an object in motion tends to stay in motion or an object at rest tends to stay at rest unless the object is acted upon by an unbalanced force.

Here the tendency of the object to resist in the change in the state of motion of the object is known as the inertia of the object and mass is the measure of the inertia.

Newton’s first law is called the law of inertia Because,

According to the Galileo’s Law of Inertia : Which states that - if no net force acts on an object, the object maintains in the same state of motion. This is a restatement of Newton’s First Law of Motion.

Therefore, The first law of Motion is also known as Galileo's law of inertia.
