MOTION AND TIME

Basic unit of time is

• hours

• seconds

• minutes

• all of the above

The instrument installed in a car for measuring the distance travelled by the car is called:

• barometer

• speedometer

• anemometer

• odometer

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

• sand clock

• sundial

• pendulum clock

• water clock

The slope of a distance-time graph of a moving object indicates:

• distance moved by the object

• time taken by the object

• speed of the object

• position of the object

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

• Rectilinear motion

• circular motion

• periodic motion

• rotational motion

The distance moved by an object in a unit time is called

• Distance

• Displacement

• Time

• Speed
