How is inertia related to mass?

Inertia is fundamentally linked to mass as it is defined as the property of an object that resists changes to its state of motion. This means that an object with mass will have a tendency to remain at rest or to continue moving at a constant velocity unless acted upon by an external force. The greater the mass of an object, the greater its inertia, which means it will require a larger force to change its motion. Thus, this connection highlights that inertia is directly dependent on the mass of an object, making the statement regarding inertia being a property of an object with mass accurate. In this context, inertia is not just an abstract concept; it is a measurable characteristic that increases with mass, which is vital for understanding dynamics and mechanics in engineering.
