The velocity-time graph for part of a train journey is a horizontal straight line. What does this tell you about its acceleration ?
What can you say about the motion of a body if:
its displacement-time graph is a straight line ?
Given alongside is the velocity-time graph for a moving body :
Find :
(i) Velocity of the body at point C.
(ii) Acceleration acting on the body between A and B.
(iii) Acceleration acting on the body between B and 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 :
Diagram shows a velocity – time graph for a car starting from rest. The graph has three sections AB, BC and CD.
From a study of this graph, state how the distance travelled in any section is determined.
A train starting from rest picks up a speed of 20 ms−1 in 200 s. It continues to move at the same rate for the next 500 s and is then brought to rest in another 100 s.
- Plot a speed-time graph.
- From graph calculate
(a) uniform rate of acceleration
(b) uniform rate of retardation
(c) total distance covered before stopping
(d) average speed.
The area of the right triangle under a speed-time graph is 500 m, in a time interval of 20 s. What is the speed of the body? Is the motion uniform or non-uniform?
The graph of one quantity versus another result in a straight line. How are the quantities related to each other?
Draw distance-time graph to show:
Uniform velocity
