caption:\
These diagrams show four different blocks sliding in different \
directions over rough surfaces. What is the direction of the friction \
force on each block? Drag the arrows to match the blocks to the \
friction forces.<p>
feedback:\
Correct. The direction of the friction force is always opposite to \
that of the motion. Friction opposes motion.<p>

caption:\
The velocity-time graphs for three spheres falling through air are \
shown. Each sphere reaches a different terminal velocity. Drag the \
arrows to match each of the spheres below to the correct velocity-time \
graph.<p>
feedback:\
Correct. The terminal velocity depends on the cross-sectional area and \
mass of the sphere. The sphere with the largest cross sectional area \
and smallest mass will have its weight balanced by air drag at the \
lowest velocity.<p>
