When objects move through fluids, they have to overcome the friction acting on them, due to which they lose energy. So, efforts are made to minimize the friction. For this, the objects are given special shapes. As we know, birds and fishes have to move about in fluids all the time. Their bodies must have evolved to shapes which would make them lose less energy in overcoming friction. Such shapes are called streamlined shapes. This is the reason ships and aeroplanes are given a streamlined shapes so that minimum energy is lost while moving through water and air respectively.

Why can you slide down a slide faster when you sit on a plastic of fiberglass mat?
The idea here is that friction is reduced.
Is friction useful when you are on a slide?
if there was no friction on a slide, you would gain speed and slide off and depending on the slide (such as a water slide) kill yourself. too much friction makes it boring.
When do you need a little friction?
You need a little friction when you are going down a water slide and much more
How can you reduce the amount of friction on a slide?
One of the things you could do is you could put soap and water on the slide.
How are friction and gravity involved in a water slide?
Friction is in the contact made by the water and what ever it makes physical contact with. Gravity causes the direction in which the water slides.
How can friction on a slide be reduced?
Water is as far as it goes.
What forces are acting on you when you slide down a water slide What type of friction is present If the water slide was dry?
fluid friction
What type of friction is present when you slide down a water slide?
Fluid friction

What reduced by friction?
efficency is reduced by friction.

If a water slide was dry how would the friction be different?
Water can absorb friction because it's wet and slippery. When things are dry, there nothing slippery or wet to absorb the friction, so the friction becomes stronger.
Is Friction reduced between polished surfaces?
when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
Is friction useful when are going down a slide?
Friction will cause heat, so you will slide and have a warm behind but friction will also slow you down on a slide
