The equipment football players drag across the field when they are training is called football sleds. They use this as a way to strengthen their defensive line.

it is a short in cut by a receiver
Airplanes try to reduce drag so they can cut back on fuel costs, and shave time off their route.
A curl in football is a receiver's route where he will usually run about five yards then turn around.
If you do not know, then you are a truly stupid imbocile.
It is a passing route where you run diagonally away from the QB.
A football and a golf ball are both faster than a book, even if kicked with the same force. Between a football and a golf ball the winner will be the golf ball, because the football has much more drag.
Make a pile of American Footballs and drag the boss through the football pile
if you have a paper map, then using string to trace the route then measuring it, then converting that distance to the known map scale will work. Otherwise google maps does a pretty good job, if you drag the route to the streets you want to use.
Once the football is in air, assumed quiet, it is acted upon by at least two forces -- gravity and air friction/drag.
