An object undergoes an acceleration of 8 ms-2 starting from rest. Distance traveled in 1 s is :
2
4
6
8
1/2
1/4
1/3
2/3
A body goes from A to B with a velocity of 20 m/s and comes back B to A with a velocity of 30m/s.
The average velocity of the body during the whole journey is
0
25m/s
24m/s
NOTA
If an object covering distances in direst proportion to the square of time lapsed, then the acceleration is
INCREASING
DECREASING
CONSTANT
NOTA
Distance travelled by a freely falling body is proportional to :-
mass of the body
square of the acceleration due to gravity
square of the time of fall
time of fall
The rate of change of displacement with time is :-
speed
acceleration
retardation
velocity
Which of the following is not vector quantity ?
Retardation
Acceleration due to gravity
Average speed
Displacement
If the time-displacement graph of a particle is parallel to the time-axis then velocity of the particle is :-
infinity
unity
equal to acceleration of the body
zero
In the velocity-time graph, AB shows that the body has
uniform acceleration
non uniform retardation
uniform speed
initial velocity OA and is moving with uniform retardation
