• 2.4 s

• 1.6 s

• 0.16 s

• 16 s

Motion which repeats itself in a regular intervals of time is called ..............

• Linear motion

• circular motion

• periodic motion

• irregular motion

Observe the figure.

The time period of a simple pendulum is the time taken by it to travel from

• A to B and back to A

• O to A, A to B and B to A

• B to A, A to B and B to O

• A to B

The most appropriate unit for expressing the speed of a space rocket is:

• m/s

• km/s

• km/h

• km/min

The measurement of small time intervals became possible with the development of :

• sand clock

• sundial

• pendulum clock

• water clock

The clocks and watches which are used for measuring time are based on :

• Rectilinear motion

• circular motion

• periodic motion

• rotational motion

The time taken by the pendulum to complete one oscillation is called its

• duration

• displacement

• time interval

• time - period
