Children running a race on a straight track will have a straight line motion. In straight-line motion the body covers the distance in only one direction. Children on a merry-go-round are moving in a circular path around a fixed point such that the distance between the fixed point and the children is constant. Such a motion is called circular motion. Children swinging on a sea-saw are moving to and fro about a mean position. Such a motion is called oscillatory motion. An oscillatory motion is periodic as the oscillation repeats after a regular interval of time. A B (a) Straight-line motion iii. Children running a race (b) Circular motion ii. Children on a merry-go-round (c) Oscillatory motion i. Children swinging on a sea-saw
