What characterizes an inertial reference frame?
Understand the Problem
The question is asking for the defining characteristics of an inertial reference frame in physics. We need to identify the correct property among the provided options that accurately describes such a frame.
Answer
An inertial reference frame is one where a body moves at constant velocity unless acted upon by forces.
An inertial reference frame is characterized by the property that a body not subjected to external forces will move in a straight line at a constant velocity. It aligns with Newton's first law of motion, and such frames are either at rest or moving with constant velocity.

More Information
An inertial reference frame is crucial for applying Newton's laws of motion accurately. In these frames, objects are observed as moving uniformly unless external forces act on them, which is a fundamental concept in classical mechanics.
Tips
A common mistake is confusing inertial frames with non-inertial frames, where fictitious forces, like the Coriolis force, appear due to the acceleration of the frame.
