Question

the tendency of undisturbed objects to stay at rest or to keep moving with the same velocity is called; A) velocity B) momentum C) inertia D) force

Answer 1

C) inertia...

perhaps it helps

Answer 2

Answer :- (c) Inertia.

explanation :- according to Newton's first law of motion, every bodies have nature to maintain inertia of rest or motion with constant velocity untill there is no net force applied on that body.

from above rule , we understand that the tendency of undisturbed object to stay at rest or keep moving with the same velocity is called inertia.

hence, option (c) is correct.
