Question

What should a free-body diagram look like for a skydiver that is still speeding up as he falls?

There is an arrow up for air resistance and an arrow down for gravity. The arrows are the same length.


There is an arrow up for air resistance and an arrow down for gravity. The arrow up is longer than the arrow down.


There is an arrow up for air resistance and an arrow down for gravity. The arrow up is shorter than the arrow down.


There is only an arrow down for gravity.

Answer 2

When you draw a free body diagram, you draw longer arrows
for stronger forces, and shorter arrows for weaker ones.

If the skydiver's falling speed is still increasing, you can tell that
the downward force of gravity acting on him is still greater than the
upward force of air resistance.

So on the diagram, there is a shorter arrow up for air resistance
and a longer arrow down for gravity. (Choice #3)
