heskey time
Relative to its surface, friction is constant (this is known as the friction constant). The speed is decreasing on an object because friction is acting on it over a period of time, not because friction is getting stronger.
Yes, Theres no way that there could be friction without the object moving
Without friction you - and everything else - would simply slide off all the time.
It slows your speed down every time your feet touch the ground.

Friction. Friction would affect how fast a car stopped (i.e. lots of friction equals fast stopping). The friction would be affected by the road conditions (icy roads less friction), tire condition (wore down gives less friction), mass of car (as if the mass is large it will have more momentum and therefore will be harder to stop, a=F/m so if mass is large deceleration will be smaller) and the reaction time will affect the total stopping time (but not the braking time).
yes both can occurs at same time.
Yes. -- Force when you lift something. -- Friction on the soles of your shoes when you walk. -- Gravitation all the time.
Friction between water and hose slows the water.
friction/thermal transfer
Static friction is the force that is the greatest. This is because it opposes motion the strongest between the various types of friction.
