b. When you stand up from a kneeling position quite suddenly, you sometimes experience a sense of
light-headedness. We can investigate the physical mechanism behind this. If you rise quickly enough

experience between brain and heart? Why might this result in dizziness?
c. What maximum acceleration can you experience before blood can no longer reach the height of your
brain?
