Question

What is another name for the first law of motion? and why is it given that name?

Answer 1

Hint : We know that Newton's motion laws include three laws. It explains the relationship between an object's motion and the forces acting on it in classical mechanics. They were used by Newton to describe and investigate the motion of a variety of physical structures and systems, laying the groundwork for Newtonian mechanics.

Complete Step By Step Answer:
According to Newton's first law, unless acted upon by an exterior force, an object stays at rest or continues to travel at a constant velocity.
Sir Isaac Newton best-illustrated inertia in his first law of motion. The concept of inertia also says that it is a physical property that causes a body to resist any force that might cause it to alter its motion. Both a body at rest and one in motion are in opposition to forces that could induce acceleration. Changes in the object's speed or direction of motion are included. One example of this property is objects' tendency to continue traveling in a straight line at a constant speed even though no forces act on them.
The theory of inertia is a fundamental concept in classical physics that is still used to explain how objects move and are influenced by applied forces.
So, we understood that, as the first law of motion defines inertia, the first law of motion is often referred to as the Law of Inertia.

Note :
Remember Newton's first law of motion and the definition of inertia. The first rule states that an object at rest stays at rest, and an object in motion stays in motion apart, acted on by a net external force. Inertia is a physical property that causes a body to resist any force that might cause it to alter its motion.
