Explanation:

Inertia is a fundamental concept in physics. According to Newton's first law of motion, an object at rest will stay at rest and an object in motion will stay in motion with a constant velocity unless acted upon by an external force. Velocity is a vector quantity that includes both speed and direction. Inertia specifically refers to an object's resistance to changes in its velocity (whether it's a change in speed or direction). Resistance to changes in acceleration is related to mass and force (from \(F = ma\)), but the direct definition of inertia pertains to velocity changes. Accelerating when a force acts on it or slowing down when a force acts on it are descriptions of how an object's motion changes due to forces, not what inertia itself is.

Answer:

resist changes in velocity.
