Question

Inertia is the property of a body which preserves its state of motion or uniform motion in a straight line. The following factors tell me about inertia.
I. Greater the mass of a body, greater is its inertia.
II. Greater the inertia of a body, the less will be the acceleration produced by a given force.
III. The law of inertia is the same as Newton's first law of motion.
Which combination is true?

• A. I and III only
• B. I and II only
• C. I, II and III
• D. II and III only

Answer 1

Answer: (C)

I, II and III

$\text{Inertia has following properties:-}$

$\text{(a) The more inertia than an object has, the}$

$\text{more mass that it has.}$

$\text{(b) Greater the inertia of a body, the lesser will}$

$\text{be the acceleration.}$

$\text{(c) Law of inertia is same as Newton's first}$

$\text{law of motion.}$

$\text{So, in the given question option (I) (II) \&}\left(III\right)$

$\therefore \text{option (c) is correct.}$
