Concept:The resistance offered by a body to any change in its state of rest is called inertia.
Explanation:A body at rest tends to remain at rest because of its inertia.
This tendency continues unless an unbalanced external force acts on it.
Inertia is not a force, but a property of matter.
Friction is a contact force that opposes motion.
Impulse is the product of force and time, and it changes momentum.
Momentum is the product of mass and velocity, given as
p=mv.
Only inertia explains why a stationary body resists being set into motion.
Thus, the correct term for this tendency is inertia.
Answer:C. inertia
