An elephant and a feather fall through the air. The force of air resistance is
1) greater on the feather
2) greater on the elephant
3) the same on each
because
4) the feather weighs less.
5) the elephant encounters more air because of his greater size and speed.
6) each is under the influence of gravitational force alone.
Question 2
When the spool is pulled to the left, it accelerates toward the
1) right,
2) left,
which illustrates the fact that
3) for every force there is an equal and opposite reaction force.
4) net force and acceleration act in the same direction.
