Friction
examples
don't slip when we walk
accelerate
turn
brake
causes metal to wear away
rubbing hands together to keep warm
taps
Drag
acts against an object when it moves through liquid or fluid
faster an object moves the more drag it experiences
air resistance
same as drag just in the air
can be reduced by streamlining
increase in area decreases air resistance
varibles
independent
change
dependent
changes
control
thing you keep the same
lubrication
Applying a slippery substance to two surfaces to reduce friction.
oil
act in the opposite direction to movement
make it more difficult for objects to move
contact force
the higher the friction surface the more force which is needed
use motor oil to stop this
