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

2. What does the slope of a velocity-time graph represent?

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

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

• 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
