    1. What are the units for the slope of a velocity-time graph?

    ± m/sec^2

    2. What does the slope of a velocity-time graph represent?acceleration (positive or negative)

    3. What are the units for the area of an acceleration-time graph?

    m/sec^2*sec = m/sec

    4. What does the area of an acceleration-time graph represent?

    velocity

    1.  It depends entirely on the units that YOU chose for the vertical axis and the horizontal axis.  For example if the vertical axis ( velocity) was in miles per hour and the horizontal axis was in seconds then the gradient would be Miles per hour per second.

    2. The slope is an acceleration.  ( rate of change of velocity)

    3. You should ONLY do this if you ensure that the units of the vertical and horizontal axes are compatible.  ie m/s^2 on the vertical axis is compatible with seconds on the horizontal axis.  km/hr^2 on the vertical axis is compatible with hours on the horizontal axis. 

    4. If you choose wisely the units are units of Velocity.

    1. velocity/time = (m/s)/s = m/s²

    2. acceleration

    3. acceleration x time = (m/s²)xs = m/s

    4. velocity
