Final answer:
A) a person's past experiences.
A frame of reference in physics is a coordinate system or set of axes that is used to describe the position, motion, and interactions of objects. It is the point from which motion is observed and measured.
Step-by-step explanation:
A frame of reference in physics is a coordinate system or set of axes that is used to describe the position, motion, and interactions of objects. It is the point from which motion is observed and measured. A frame of reference is determined by the observer's choice of what is considered to be at rest or in motion. It does not rely on a person's past experiences, future experiences, style of dress, or physical make-up.
For example, if you are in a moving car and looking out the window at houses going past, your frame of reference would be the car because that is what you are in and what you are observing the motion from.
So, the correct answer is A) a person's past experiences.
