If the velocity of the body decreases non-uniformly then the slope of the velocity-time graph will have |
different values
same values
zero valves
constant valves
|
8 |
If the slope of the velocity-time graph increases at constant rate with time, then the body is said to have |
uniform deceleration
uniform negative acceleration
average acceleration
uniform positive acceleration
|
9 |
When a body is moving with uniform positive acceleration, the velocity- time graph is a straight line. Its slope is |
zero
negative
positive
non-existing
|
10 |
The three equation of motions are useful only for |
linear motion with increasing acceleration
line motion with uniform acceleration
linear motion with zero acceleration
linear motion with varying acceleration

A body starting from rest covers a distance of 0.45 Km and acquires a velocity of 300 Kmh-1. its acceleration will be |
7.71 m s<sup>-2</sup>
0.5m s<sup>-2</sup>
0.15m s<sup>-2</sup>
0.092m s<sup>-2</sup>

The area under line velocity-time graph is numerically equal to the |
speed of the body
acceleration of the body
distance covered by the body
none of them

13 |
The slopes of the tangent at any point on the curve gives the value of the |
average velocity at that point
instantaneous velocity at that point
average acceleration at that point
instantaneous acceleration at that point
|
14 |
When body moves with increasing acceleration, its velocity time graph is a |
straight line
horizontal straight line
vertical straight line
curve

Graphs which are used to illustrate the variation of velocity of an object with time are called |
distance time graphs
speed time graphs
velocity time graphs
acceleration time graphs
