CBSE - Motion

1 Motion Without actually calculating the speed, can you guess in which time interval is the body moving fastest?

(1) 20-40 s
(2) 40-50 s
(3) 90-100 s
(4) 80-90 s

2 Motion  If the speed-time graph is a straight line parallel to the time axis, then the body is
(1) accelerated motion
(2) in uniform motion
(3) non-uniform acce le rate d motion
(4) at rest

3 Motion In 10 minutes, a car with speed of 60 kmh^–1 travels a distance of -

(1)  6 km
(2)  600 km
(3)  10 km
(4)  7 km

4 Motion The speed-time graph for a particle moving at constant speed is a straight-line ________ to the time axis.

(1) perpendicular
(2) parallel
(3) inclined
(4) aligned

5 Motion What is the speed of the object in the 10 second interv al from 40-50 seconds?

(1) 2 m/s
(2) 1 m/s
(3) 0.25 m/s
(4) 0.5 m/s

6 Motion The correct velocity-time graph for zero acceleration is:

7 Motion A body starts from rest at time t = 0, the acceleration time graph is shown in figure. The maximum velocity attained by the body will be :

(1) 110 m/s
(2) 55 m/s
(3) 650 m/s
(4) 550 m/s

8 Motion When the distance travelled by an object is directly proportional to the time, it is said to travel with-

(1)  zero velocity
(2)  constant speed
(3)  constant acceleration
(4)  uniform velocity

9 Motion Area under a v – t graph represents a physical quantity which has the unit:
(1) m²
(2) m / s
(3) m / s²
(4) m

10 Motion A body of mass 2 kg is moving on a smooth floor in straight line with a uniform velocity of 10 m/s. Resultant force acting on the body is -


(1) 20 N
(2) 10 N
(3) 2 N
(4) zero
