Sagot :
It is dependent upon the object's mass. The greater the mass of the object greater will be the inertia of the object, and hence it's resistance to change in motion as well.
Answer : Mass
Explanation : An object's resistance to change in motion is solely dependent on the mass of the quantity. The tendency to resist the change in motion is called as inertia. Which is highly influenced by the factor called "mass" of the object. The mass of the quantity will decide the direction for change in the motion of a particular object.
