frame of reference

Question

Which one is right

• the total ground covered by an object during its motion

• A set of points a person uses to determine if an object is in motion. We call those points "Reference Points"

• the study of how things move
the shortest length of a path taken by an object from one point to another

Answer 1

All of the statements are correct definitions of a frame of reference, but they may be used in different contexts.

- The total ground covered by an object during its motion refers to the distance traveled by the object.
- A set of points a person uses to determine if an object is in motion (reference points) is used to establish a frame of reference for analyzing the motion of objects.
- The study of how things move may involve using frames of reference to analyze and describe the motion of objects.
- The shortest length of a path taken by an object from one point to another may be considered in the context of distance traveled or displacement in a frame of reference.
