A reference point is a stationary object or a specific location used as a baseline to determine the position and motion of another object. It allows for the measurement and observation of an object's movement relative to that reference point. For example, if you describe a car moving down a road, the road itself or a nearby tree can serve as a reference point to indicate how far the car has traveled and in what direction. In summary, the reference point provides context and helps to clearly define motion by establishing a frame of reference.
