CBSE - Motion

1 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

2 Motion At the top of its path a projectile has
(1) no acceleration
(2) acceleration in the upward direction
(3) acceleration in the downward direction
(4) acceleration in the horizontal direction

3 Motion  A body freely falling from rest has a velocity v after it falls through a height h. The distance it has to fall further for its velocity to become double is -

(1)  3 h
(2)  6 h
(3)  8 h
(4)  10 h

4 Motion The ratio of the heights from which two bodies are dropped is 3:5 respectively. The ratio of their final velocities is:
 (1) 9 : 25
 (2) √ 3 : √ 5
 (3) 5 : 3
 (4) √5 : √3

5 Motion 
Which motion does the graph of distance and time shows for accelerated motion?
(1) Non-uniformly accelerated
(2) Constant accelerated
(3) Uniformly accelerated
(4) Uniformly retarded motion

6 Motion A particle is traveling with a constant speed. This means-

(1)  Its position remains constant as time passes
(2)  It covers equal distances in equal interval of time
(3)  Its acceleration is zero
(4)  It does not change its direction of motion

7 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

8 Motion The equations of motion can be derived by using:
 (1) Distance– time graph
 (2 Velocity – time graph for non-uniform acceleration
 (3) Displacement time graph
 (4) Velocity – time graph for uniform acceleration

9 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

10 Motion The area enclosed by velocity-time graph and the time axis will be equal to the magnitude of
(1) displacement
(2) speed
(3) acceleration
(4) distance
