Identify the motion of the block shown in the figure.

 

Observe at the objects around you. You may select some of the objects from the following list: Cat, butterfly, dog, vulture, owl, cow, your hand, a small baby, a flag, tree leaves, air, flower, water, a house, a factory, a lizard, a stone, a horse, a girl, a boy, a ball, a bat in a batsman's hand, fielder in a cricket field, a moving train, a sewing machine, a wall
clock, hands of a clock, the moon, the sun and stars .You might have observed that some of them are at rest while others are in motion. List out all these objects as at rest or in motion in Table 2.1.

In Activity 1, how did you decide whether an object is in motion or at rest? You might have noticed that the bird is not at the same place after some time, while the wall clock is at the
same place. On this basis, you can decide whether an object is at rest or in motion.
