Question

Assertion : The slope of distance-time graph gives acceleration of the body.

Reason : Greater the slope of distance-time graph, more is the speed of thebody


Assertion : Newton’s equations of motion hold true for uniformly accelerated motion only.

Reason: The equations of motion do not apply to freely falling body as its motion is not uniformly accelerated.


Assertion: In mechanics, the quantities like length, mass and time are taken as fundamental quantities

Reason: Length, mass and time cannot be expressed in terms of one another.


Assertion: SI system is a coherent system of units

Reason: In SI, all derived units can be obtained by multiplying and dividing the basic and

supplementary units.​
