CBSE - Motion

1 Motion The area under the speed-time graph gives the ________.
(1) velocity
(2) distance
(3) acceleration
(4) time

2 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

3 Motion The velocity time graph of two bodie s A and B traveling along the +x direction are given in
the figure . Which body has a greater acceleration?

(1) Body A has a greater acceleration
(2) Body B has a greater acceleration
(3) Both A and B have same acceleration
(4) Acceleration cannot be predicted from the given graph

4 Motion On the distance-time graph, the Y-axis should be labelled as:
(1) Distance
(2) Displacement
(3) Speed
(4) Time

5 Motion The following position-time graph of an object shows that the body

(2) Has non-uniform motion.
(3) Has uniform motion.
(4) Is at rest.

6 Motion 

The time interval between 24 to 52 seconds when the body travels the fastest is?
(1) 28 to 32 s
(2) 40 to 50 s
(3) 42 to 52 s
(4) 32 to 42 s

7 Motion 40 A body starts falling from height 'h' and travels distance h/2 during the last second of motion. The time of travel (in sec.) is-
(1) √ 2 -1
(2) 2 + √2
(3) √2+ √3
(4) √3 +2

8 Motion In figure BC represents a body moving-
