Objects tend to continue in their current state, if at rest or uniform motion. What is the term for this tendency?

The term for this tendency of objects to continue in their current state, whether at rest or in uniform motion, is inertia. Inertia is a fundamental property of matter, described in Newton's First Law of Motion, which states that an object will remain at rest or move at a constant velocity unless acted upon by a net external force. This principle illustrates the resistance of any physical object to changes in its velocity. Inertia depends on the mass of the object; the greater the mass, the greater the inertia. In practical terms, this means that heavier objects require more force to change their motion compared to lighter objects.
