CBSE - Motion

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

(1) No such inference can be made from the graph.
(2) Has non-uniform motion.
(3) Has uniform motion.
(4) Is at rest.

2 Motion The distance travelled by a body is directly proportional to the time, then the body is said to have -

(1)  Zero speed
(2)  Zero velocity
(3)  Constant speed
(4)  None of these

3 Motion What is the slope of distance-time graph when object is at rest?
(1) Decreases continuously
(2) Zero
(3) Increases continuously
(4) One

4 Motion In which of the following graphs are both runners moving at the same speed?

(1) Graph-C
(2) Graph-A
(3) Graph-D
(4) Graph-B

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 For the velocity time graph shown in figure,

the distance covered by the body in the last two seconds of its motion is what fraction of the total distance covered in all the seven seconds ?

(1)  1/2
(2)  1/4
(3)  1/3
(4)  2/3

7 Motion In a given velocity-time graph, what happens to velocity between C and D?

(1) Velocity is infinite
(2) Velocity is decreasing
(3) Velocity is increasing
(4) Velocity is constant

8 Motion A body is dropped from certain height from a uniformly ascending balloon. The correct graph showing variation of velocity with time for body is :

9 Motion In figure BC represents a body moving-

(1)  Backwards with uniform velocity
(2)  Forward with uniform velocity
(3)  Backward with non-uniform velocity
(4)  Forward with non-uniform velocity
