All objects resist a change in motion. That is Newton's first law of motion. It requires only that the object have mass. An object that is not acted on by an external force will continue in it previous state of straight line motion. The property that all object have that resists a change in motion is called inertia. The quantitative measure of the inertia of a body is called its mass. This answer applies to movement through space. There is a similar explanation for rotational motion.
Acceleration is the change in an ogjects speed or a change in an objects direction of motion or both of these. If instead of speed you use the word velocity , which is both an object's speed and its direction of motion, then you could say "acceleration is the change in an objects velocity" and that would cover all the possibilities in one statement.
they all have random energy;)
This kind of force acting on a object cause a change in the objects motion
Relative motion is the concept that the motion of all objects is relative to other objects. If you are sitting still right now you are not moving relative to the earth, however you are moving relative to sun.
Inertia is the tendency of all objects to resist change in motion.
Inertia is the tendency that all objects resist a change in motion
All objects resist changes in their state of motion

The word is "motion", part of Newton's First Law defining inertia.
acceleration.
First of all, it's inertia. Inertia is the tendency of matter to resist a change in motion, hence, an object at rest will stay at rest, and an object in motion will stay in motion. The bigger an object is, the more inertia it has.
Inertia is the inherent property of a body that makes it oppose any force that would cause a change in its motion. A body at rest and a body in motion both oppose forces that might cause acceleration. The inertia of a body can be measured by its mass, which governs its resistance to the action of a force, or by its moment of inertia about a specified axis, which measures its resistance to the action of a torque about the same axis.
