The inertia of an object tends to cause the object
(a) to increase its speed
(b) to decrease its speed
(c) to resist any change in its state of motion
(d) to decelerate due to friction
Ans. C
Sol.
As defined in Newton’s first law, everybody has the property of inertia.| This property of inertia of the body tries to maintain the state of rest or motion with constant velocity. The property of inertia opposes the change in the state of rest or uniform motion. A force is required to change the state of rest or uniform motion.
For bodies with more inertia required more force to change its velocity. We can say that inertia is the property which resists change in motion.
Physically inertia can be seen as a mass of the body.
Correct option of this question is C.
