The best illustration used to be: Remember when you
rode your coaster wagon downhill alone and also with
a buddy in it? It always went faster with two people.

Who knows anything about coaster wagons anymore?

Gene:

1: A glider's best glide ratio is unaffected by its
weight.
2: However, a heavier glider flies and sinks faster
at

3: When lift conditions are strong, the pilot accepts
the
higher sink rates to achieve higher speeds over the
ground.
