Surfaces, even seemingly smooth ones,
have microscopic unevenness.
The unevenness of two touching surfaces
catch on each other,
and this produces friction, friction, woah friction.
This creates heat and electricity,
of a static variety.
There’s no such thing as perfect efficiency,
and all because of friction, friction, woah friction.
Coulombs Law of friction requires ideal conditions, you see,
for kinetic friction not to be affected by sliding velocity.
The force that resists the relative motion,
or the tendency to such motion of two bodies,
or substances in contact
causes friction, friction, woah friction.
All work is movement,
and all movement causes

Friction
Friction, friction, beneficial when manifest as traction.
Frictional force causes negative acceleration,
which is less useful.
From time immemorial these musicians have stood at the gateway of nonsense begging peanuts. Spending most of their time
trapped in force fields and vortices, occasionally they are released to stalk the streets of Leeds. On such occasions you might hear the plaintive cry of Sam’s tuba, the mournful crow of Dean’s ukulele, the excited jazzy croaking of Bob’s piano or the purr of Matty’s drums....more
