Show by means of graphical method that: v = u + at, where the symbols have their usual meanings.
Derive the following equation of motion by the graphical method : v2 = u2 + 2as, where the symbols have their usual meanings.
For uniform motion _________
The area under a speed-time graph in a given intervals gives the total distance covered by a body irrespective of its motion being uniform or non-uniform.
What does the slope of speed-time graph indicate?
Draw distance-time graph to show:
Decreasing velocity
Sketch the shape of the velocity-time graph for a body moving with:
Uniformly velocity
(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.
State whether true or false. If false, correct the statement.
The velocity – time graph of a particle falling freely under gravity would be a straight line parallel to the x axis.
The area of the velocity-time graph gives the displacement of the body.
