    What does the area of an 'acceleration- displacement' graph represent?

    A)  Distance                      

    B)  Velocity

    C) \[\frac{{{v}^{2}}-{{u}^{2}}}{2}\]       

    D)        \[\frac{v-u}{t}\]

    Correct Answer: C

    Solution :

     \[{{v}^{2}}-{{u}^{2}}=2aS\],\[\therefore \]\[a\times S=\frac{{{v}^{2}}-{{u}^{2}}}{2}\](\[a\times S\] is the area of the acceleration-displacement graph).
