When a body is stationary.


Draw velocity – time graph for the following situation:

When a body is moving with variable velocity, but uniform acceleration.


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

  1. deceleration
  2. acceleration
  3. total distance covered by ball
  4. average velocity.

Draw the following graph:

Interpret the following graph:


What can you say about the motion of a body if:
Its time-displacement graph is a straight line.

(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.
