Inertia is the tendency of an object to continue to move, or stay at rest, unless affected by an externalÊforce. Inertia is related to the mass of an object so objects with greater mass have more inertia.
This is rotational inertia. When inertia forces an object to rotate, it will continue to do so until another force acts upon it.
The only item that affects inertia is mass.

AnswerA Trick Question. While at rest, an object has no inertia.
The property of an object is the features that define. Most objects are defined by physical properties like shape, size, weight and so on.
His mass.
If object "A" is heavier than object "B", then object "A" also has more mass (weight = mass x gravity, and gravity can be assumed to be constant for most practical purposes). And more mass causes more inertia - inertia is the direct result of the amount of mass.
inertia just depends on mass. Big mass=hard to move.
Simple Answer:Mass and inertia are essentially the same thing.Better Answer:Inertia is a characteristic of any physical object and mass is the quantitative measure of the characteristic.This is embodied in Newton's first law of motion. We can say this as follows.An object in motion will resist a change in motion and a body at rest will remain at rest unless acted on by some external influence. This property of maitaining a state of motion is called inertia in physics. The external influence that can change a state of motion is a force. To say that some objects resist a change of motion more than others is to say that some objects have more inertia than others.Fortunately, this characterization of inertia is more than qualitative. There is a precise physical measure of inertia and it is called mass.This is contained in Newton's second law of motion. We quantify the concept of motion by defining velocity. We quantify change in motion as acceleration. We quantify mass as the ratio of the acceleration to force.F=ma.m=F/a.The dramatic characteristic of the relationship is that if you quantify the mass of an object by applying twice the force, you get twice the acceleration and hence the same mass.To be slightly more specific we must also note that force and acceleration are both vector quantities and the above relationships are valid for both magnitude and direction of force and velocity.Note: Two comments are appropriate to be very technical. First, this explanation ignores the possible distinction between mechanical mass and gravitational mass. Secondly, the theory of relative has an equally significant understanding of mass that is not discussed here. These technical points do not invalidate the description above and may be ignored unless engaged in the most sophisticated and expert levels of discussion.
