Motion with Uniform Acceleration

Knowledge Check

  • 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

    A
    `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)`

    PASSAGE-I : A body is said to be in motion when its position changes continuously with respect to a stationary object taken as reference point. A body has a uniform motion if it travels equal distance in equal intervals of time, no matter how small these time intervals may be. The distance-time graph for uniform motion is a straight line. A body has a non-uniform motion if it travels unequal distance in equal intervals of time. The distance-time graph for a body having non-uniform motion is a curved line. The distance-time graph for a uniform motion is
