Review: Oscillatory Motion

The motion which repeated at equal intervals of time.

• periodic motion

• transport motion

• curved motion

• none

The maximum displacement made by oscillating body away from its rest position is ...................

• amplitude

• frequency

• periodic time

• complete oscillation

The complete oscillation include ………….. displacements.

• one

• two

• three

• four

The speed of pendulum ------------- if it is moving away from rest position.

• increase

• decrease

• not affected

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

• transitional motion

• oscillatory motion

• wave motion

• circular motion

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

• decreases when it goes far from its rest position

• increases when it goes far from its rest position

• remains constant

• will reach its minimum value when it passes its rest position

The maximum displacement achieved by the oscillating body away from its rest position is ....................

• amplitude

• frequency

• periodic time

• complete oscillation

The frequency of the oscillating body is measured by a unit called…

• Hertz
• watt/m
• decible
• m/sec

If the frequency of an oscillating body is 6 Hz, the periodic time is…

• 3 sec
• 1/3 sec
• 1/6 sec
• 6 sec

If the periodic time of an oscillating body is 1/6 seconds , this means that…..

• (a )an oscillating body makes 6 complete oscillations in a minute
• (b) the frequency of an oscillating body equals 6 Hz
• ( c) the oscillating body makes 360 complete oscillations in one minute
• (b) and (c ) are correct
