Air resistance; the friction occurring on something moving through air
Example; the effect of air resistance on train ,car, rocket, and aircrafts
When an object moves so fast in the air the friction force between this object and air increase ,
A: because the area of surface exposed to air increases
WHATER RESISTANCE:it is the friction occurring on something moving through water
EXAMPLE:the effect of water resistance on the fish and ships
ADVANTAGES OF FRICTION
1friction help us to control the car speed
2 friction is help to light a match
3 friction prevents our shoes from slipping on the ground
