The area under acceleration-time graph gives

For a particle in motion which of the following speed-time graphs can be realized in practice :

For a uniformly retarded motion, the velocity-time graph is :

The velocity-time graph of a bosy moving along a straight line is given below find: (a) Average velocity in whole time of motion (b) Average speed in whole time of motion (c ) Draw acceleration vs time graph. .

A : The area under acceleration - time graph is equal to velocity of object. R : For an object moving with constant acceleration, position - time graph is a straight line.

Graphs are very useful to represent a physical situation. Various quantities can be easily represented on graphs and other quantites can be determined from the graph. For example the slope of velocity-time graph represents instantaneous acceleration. For a motion with constant acceleration slope of velocity-time graph is constant. If acceleration is changing with time, slope with change and thus velocity-time graph will be a non-linear curve. Further the area of velocity-time graph gives displacement. For the above situation let t_(1) be the time of accelerated motion and t_(2) be the time or retarded motion, then the correct relation is
