A body is moving uniformly in a straight line with a velocity of 5 m/s. Find graphically the distance covered by it in 5 seconds.
Study the speed-time graph of a car given alongside and answer the following questions:
(i) What type of motion is represented by OA ?
(ii) What type of motion is represented by AB ?
(iii) What type of motion is represented by BC ?
(iv) What is the acceleration of car from O to A ?
(v)What is the acceleration of car from A to B ?
(vi) What is the retardation of car from B to C ?
A car of mass 1000 kg is moving with a velocity of 10 m s−1. If the velocity-time graph for this car is a horizontal line parallel to the time axis, then the velocity of car at the end of 25 s will be :
What does the slope of velocity-time graph represent?
Multiple choice Question. Select the correct option.
A graph is a straight line parallel to the time axis in a distance-time graph. From the graph, it implies:
Diagram shows a velocity – time graph for a car starting from rest. The graph has three sections AB, BC, and CD.
Is the magnitude of acceleration higher or lower than that of retardation? Give a reason.
The area under a speed-time graph in a given intervals gives the total distance covered by a body irrespective of its motion being uniform or non-uniform.
Interpret the following graph:
Mention the uses of the velocity-time graph.
