Is this true in other cases too?

Let us do some activities.

Activity: 1

Materials Required:
1. One 10 metres rope
2. Sketch pen

Procedure:
1. Hold one end of a long rope (10 metres) in your hand and ask your friend to hold the other end.
2. Mark a small portion on the rope with a colour.
3. Now give a sudden jerk to the rope.

Did the coloured mark change its position along the rope?    

Did you feel light and frequent jerks in your hand? Why does this happen?

Activity: 2
