Name the two quantities, the slope of whose graph give acceleration.
Draw a velocity-time graph to show the following motion :
A car accelerates uniformly from rest for 5 s ; then it travels at a steady’ velocity for 5 s.
The velocity-time graph for part of a train journey is a horizontal straight line. What does this tell you about the trains velocity.
Define speed. What is its S.I. unit?
Draw a displacement-time graph for a boy going to school with uniform velocity.
Diagram shows a velocity – time graph for a car starting from rest. The graph has three sections AB, BC and CD.
Compare the distance travelled in section BC with the distance travelled in section AB.
Draw the following graph:
Speed versus time for a non-uniform acceleration.
Which of the following graphs represents a motion with negative acceleration?
Derive the equation
S = ut+ `1/2` at2
Using a speed- time graph
(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.
