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 isA. `a_(1)t_(2)=a_(2)t_(1)`B. `a_(1)t_(1)=a_(2)t_(2)`C. `a_(1)t_(1)^(2)=a_(2)t_(2)^(2)`D. `a_(1)t_(2)^(2)=a_(2)t_(1)^(2)` |
