Question Vidya is enjoying her time on the swing. She notices that the greater the angle with which she starts the swinging, the greater is the speed she achieves on her swing. But where is the angle? Are you able to see any angle?
Vidya’s original position is along’the vertical line. When she starts swinging the rope of the swing is along the slanting line which makes an angle with the imaginary vertical line. The speed depends upon this angle.
