Question

Advantages and Disadvantages of Fluid Friction

Answer 1

Fluid Friction or Drag is the frictional force exerted by fluid on the objects moving through them.
Advantages of Fluid Friction:
1. , Flotation of ship,Hover crafts, hot air balloons etc which helps in transportation .
Disadvantages of Fluid Friction:
1. Fluid Friction reduces the speed of objects moving through the fluids
2. It makes speeding up harder
3. When objects, move through fluids, they loose some  energy in overcoming the fluid friction.This decreases their efficiency.
