the mass of the object determines the amount of inertia in an object. Mass determines the amount of inertia an object has. It is an object's intrinsic property to resist change. the two main things are speed and velocity. You have to factor in a bunch of smaller things too, but those don't really have much effect.
The object will continue to remain at rest until and unless a force acts on it. For example, a person might hit the object with a mallet. The force of the blow might change the object's motion, giving it both speed and direction. The property of objects described by the first law is known as inertia.
