Oscillatory motion

The movement of a swing is known as ……….

• (a) transitional motion
• (b) oscillatory motion
• (c ) wave motion
• (a) and (b)

The oscillating body moves at the two sides of its rest position, so its velocity……..

• (a) decreases when it goes far from its rest position
• (b) increases when it goes far from its rest position
• (c ) will reach its maximum value when it passes its rest position
• (a) and (c )

Kinetic energy = 1/2 X ……

All of the following are examples of oscillatory motion except………..

• motion of string
• motion of tunning fork
• motion of car
