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.
Three speed-time graphs are given below :
Which graph represents the case of:
(i) a cricket ball thrown vertically upwards and returning to the hands of the thrower ?
(ii) a trolley decelerating to a constant speed and then accelerating uniformly ?
Define speed. What is its S.I. unit?
Diagram shows a velocity – time graph for a car starting from rest. The graph has three sections AB, BC, and CD.
In which section, car has a zero acceleration?
Represent the position of a body described as at 15 m, 30o north of west, on a graph paper.
Draw the following graph:
Speed versus time for a stepped motion
Its time-displacement graph is a straight line.
Derive the equation
S = ut+ `1/2` at2
Using a speed- time graph
Figure shows the distance-time graph of three students A, B and C. On the basis of the graph, answer the following :
Will the three ever meet at any point on the road?
(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.
