Which term describes the tendency of an object to resist a change in motion?

An object's tendency to resist a change in its state of motion is called inertia. This is the basis of Newton's Laws of Motion; "An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.". The state of motion refers to the object's velocity, which is the the speed and direction. One quantifies inertia as the quantity of mass of an object. On can say that the mass of an object is a measure of how much an object resists change in its motion. The more mass an object has, the more inertia it has. That's why it is harder to push a 3 ton box as opposed to a soccer ball, or something lighter.

It is inertia. It is what is described in Newton's First Law of Motion when it says that an object will have a tendency to continue in its state of uniform motion or rest unless a resultant force acts upon it.

Inertia is the tendency of an object to resist change in motion. The greater the mass, the greater the inertia.
