Overview

In order to explain motion, we are required to define the reference point. Same set of motion can be explained in different ways depending on its reference point. If an object's motion is being examined with respect to another moving object, then the motion is the relative motion of first object with respect to the second object.

Learning objectives

After completing this module, you will be able to:
- Explain how relative motion depends on the point of reference.
- Illustrate that speed and position always depend on the point of reference.
