Draw a displacement-time graph for a boy going to school with uniform velocity.
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:
A ball is thrown up vertically and returns back to thrower in 6 s. Assuming there is no air friction, plot a graph between velocity and time. From the graph calculate
- deceleration
- acceleration
- total distance covered by ball
- average velocity.
From the velocity – time graph given below, calculate acceleration in the region AB.
Given on th e side are a few speed - time graphs for various objects moving along a stra ight line. Refer below figure. (a), (b), (c) and (d).
Which of these graphs represent
(a) Uni form motion
(b) Motion with speed increasing
(c) Motion with speed decreasing and
(d) Motion with speed oscillating.?
What can you conclude if the speed-time graph of a body is a straight line sloping upwards and not passing through the origin?
Given below are the speed -time graphs. Match them with their corresponding motions :
 |
(a) Uniformity retared motion |
 |
(b) Non-uniformity acceleration |
 |
(c) Non-uniform motion |
 |
(d) uniform motion |
(i) In speed time graph uniform motion is given by a straight line parallel to x axis so figure (a) denotes the uniform motion.
(ii) In speed time graph motion with increasing speed is shown by straight line with positive slope so figure (c) denotes the motion with speed increasing.
(iii) In speed time graph motion with decreasing speed is shown by straight line with negative slope so figure (b) denotes the motion with speed decreasing.
(iv) In speed time graph motion with oscillating speed is shown by zigzag line so figure {d) denotes the motion with speed oscillating.
The area of the velocity-time graph gives the displacement of the body.
If the velocity-time graph has the shape AMB, what would be the shape of the corresponding acceleration-time graph?
