Acceleration Due to Gravity/Earth's Surface
Therefore the force on $B$ can be expressed as:
- $F = m g$
This result famously contradicts Aristotle, who taught that heavier objects fall faster than light ones.
Apparently this never actually happened.
The fact that in the general case air resistance can not be ignored goes some way to explaining how the truth was not arrived at earlier.
Even children notice how leaves, for example, flutter gently down from on high, whereas stones tend to plummet.
