CBSE - Motion

1 Motion In case of a moving body-

(1)  Displacement > Distance
(2)  Displacement < Distance
(3)  Displacement ³ Distance
(4)  Displacement £ Distance

2 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

3 Motion 

The speed of the body in the time interval 14 to 18 seconds is
(1) 10 m/s
(2) 0
(3) 12 m/s
(4) 20 m/s

4 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

5 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

6 Motion 

The figure above shows distance-time graphs of two objects X and Y. Which object is mov ing
with greater speed?

(1) Both objects are at rest
(2) Both objects are moving with same speed
(3) Object Y
(4) Object X

7 Motion The distance travelled by the body between 0 to 20 seconds?

(1) 260m
(2) 160m
(3) 300m
(4) 60m

8 Motion 

A ball is thrown vertically upwards. Which of the following plot represents the velocity time graph of the ball during its flight, if the air resistance is not ignored ?

9 Motion The velocity-time graph of an object moving in a fixed direction is shown in the figure below.

What do you conclude about the object?
(1) Moves with a constant speed.
(2) Moves with varying speeds.
(3) Moves with a non zero acceleration.
(4) Is at rest.

10 Motion A body is said to be in non-uniform motion if it travels
(1) Equal distance in unequal interval of time
(2) Equal distance in equal interval of time
(3) Unequal distance in unequal interval of time
(4) Unequal distance in equal interval of time
