    Acceleration-Time Graph

    I have two physics questions:

    (a) What does the area under the acceleration-time graph represent? (Hint: it is NOT velocity or speed).

    (b) What is a particle doing when the graph is above or below the axis? (Hint: a graph below the axis does NOT necessarily mean deceleration).

    I suggest you review your class notes or textbook.

    (a) Change in velocity.

    (b) Above the axis: a > 0. Below the axis: a < 0. Note that if a < 0 for long enough the particle will slow down, stop and then move in the 'negative direction' ....
