    The area of the acceleration-displacement curve of a body gives

    A)  impulse                            

    B)  change in momentum per unit mass

    C)  change in KE per unit mass

    D)  total change in energy                

    Correct Answer: C

    Solution :

     Area of acceleration-displacement curve gives change in KE per unit mass. \[\frac{1}{2}m({{v}^{2}}-{{u}^{2}})=Fs=\frac{mdv}{dt}\times s\] \[\therefore \] \[\frac{\text{Change}\,\text{in}\,\text{KE}}{\text{Mass}}=\frac{dv}{dt}\times s\]
