The observation that Object A has a greater tendency to resist changes in its state of motion than Object B indicates that Object A has more inertia, which is due to having a greater mass.
When comparing Object A and Object B, with Object A showing a greater tendency to resist changes in its state of motion, this indicates that Object A has more inertia than Object B. Inertia is the property of an object to remain at rest or to maintain its state of uniform motion unless acted upon by an external force, as stated by Newton's first law, also known as the law of inertia. The measure of inertia an object possesses is directly related to its mass. Therefore, a larger mass equates to greater inertia, making it more challenging to alter the object's state of motion.
This understanding allows us to conclude that inertia dictates how much an object will resist changes in its motion, and it is not necessarily linked to the substance being solid, liquid, or gas, nor directly to the forces acting on it or the friction experienced by it.
