Question

State why newton's first law motion is also 'law of inertia'.

Answer 1

Answer:

Inertia is tendency of an object to remain itself at rest or in motion.

and Newton's First Law of Motion says that an object will remain at rest or move at a constant speed in a straight line unless or until any unbalanced force act on it.

so newton's first law motion is also called 'law of inertia'.
