Q127
What cause a moving body to resist a change in its state of motion?
A.
Displacement
B.
Acceleration
C.
Inertia
AnswerD.
Velocity
Answer: Option C
Solution
Answer: Option C
Solution:
Inertia: tendency of an object to resist changes in its velocity. An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
