The velocity-time graph of a body in motion is a straight line inclined to the time axis. The correct statement is -

• velocity is uniform

• acceleration is uniform

• both velocity and acceleration are uniform

• neither velocity nor acceleration is uniform.

From the velocity-time graph, we can determine :

• The displacement of the body in a certain time interval.

• The acceleration of the body at any instance.

• Both (a) and (b)

• None of these

From the given displacement-time graph, answer the following questions: (i) The kind of motion depicted in this graph is :

• uniform

• non-uniform

• retardation

• all of the above

(ii) The velocity between point A and B is:

• 20 ms-1

• 5 ms-1

• 10 ms-1

• 15 ms-1

The displacement at t = 3s is:

• 15 m/s2

• 12.5 m/s2

• 40 m

• 30 m

The slope of displacement-time graph gives:

• Velocity

• Acceleration

• Speed

• Displacement

In a velocity-time graph, a downward slope indicates:

• Uniform motion

• Deceleration

• Acceleration

• Constant velocity

Reyansh and Kartik are racing toy cars. At what time interval does the car have the greatest speed?

• t = 6 s to t = 9 s

• t = 1 s to t = 4 s

• t = 4 s to t = 6 s

Neha is riding her bicycle down a straight path. Velocity is determined by

• distance the object has traveled

• average speed of the object

• knowing the speed and direction of the object's motion

• instantaneous speed of the object
