Question

assignment on Inertia

Answer 1

inertia is an property of a body by virtue of which it opposes the change in its state of rest or motion

Answer 2

newton's first law of motion is called inertia.
that law Is
if an object is in moving then it will try to move continuously until any external force doesn't act on it.
Similarly, if an object is in rest then it will try to be in rest until any external force doesn't act on it.

Inertia is the resistance of any physical object to any change in its position and state of motion. This includes changes to the object's speed, direction, or state of rest.

Inertia is also defined as the tendency of objects to keep moving in a straight line at a constant velocity. The principle of inertia is one of the fundamental principles in classical Physics  that are still used to describe the motion of objects and how they are affected by the applied forces  on them.

Inertia comes from the Latin word, iners, meaning idle, sluggish. Inertia is one of the primary manifestations of mass, which is a quantitative property of physical systems. Isaac Newton  defined inertia as his first law in his Philosophy Naturalis Principia Mathematica.
