Obliquity II : turn the upper cheek

From summer downunder, for Eugi’s weekly prompt “winter”.  So great to have these prompts back! Thanks Eugi!

Friction does not oppose motion!

You can’t, of course
walk or drive, with
no friction force.
Please tell your kith
and tell your kin:
You can’t begin
without friction. Continue reading

cautionary example

or “mechanical disadvantage”:

Alas poor Spidey, poor Spidey is dead!
She’s hunted her last, and now she is spread
