Test Your Learning: Activity 1.1:
Activity: Discuss whether the walls of your classroom are at rest or in motion.
[Hint: The concepts needed to answer this question has been discussed in Lesson 1.3]
Answer: It will depend on where we take the reference point to be.
If we take the reference point on the earthâ€™s surface, then the walls will be at rest.
But if we take the reference point on the sun (or at any other point in outer space), then the walls will be in motion, since they will be moving around the sun together with the earth.
