friction affects in any Circumtances
A projectile doesn't follow a circular path. It follows a parabolic path. No part of a circle has the same shape as any part of a parabola. They're different curves.
Loss of energy. Any way friction is a necessary evil
Not sure if you mean 2 types of friction. Two types of friction can be just friction with the ground, and air friction such as drag on any vehicle, or any type of flying machine. Other objects can have air friction too, but not as much as something moving at a higher rate of speed.
Machine without any friction is an ideal machine so an ideal machine cannot have friction.
Begs the question: Same perimeter as what? There are plenty of examples of shapes that given the same perimeter length will have different areas, e.g. pick any two of the following: Circle, Square, Triangle, Rhombus, Pentagon, Hexagon...
Rolling Friction is caused by a rolling object such as a wheel when rolling over a surface. Sliding friction is cause by the brishing of an object along with the medium that it is sliding on. This can be visualize by sliding down a hill with a sled in the snow. Fluid friction, by fluid we are alluding to any substance that flows. Therefore air and water for both examples are fluid. When swimming or when is a bird is flying fluid friction is being acted upon them Good luck Stephane E. Fouche
There is 'skin friction' also know as drag. There is also lubricated friction.

Friction is most commonly known as any push or pull. There are four types of friction ; sliding friction, static friction, rolling friction, and fluid friction. Sliding friction is when something is sliding against another surface. Static friction is when there is force being applied upon a heavy object or the object is being moved on a rough surface. Rolling friction is when something is rolling on a surface and friction slows it down. Finally, fluid friction is when an object is being slown down on or in water, air, or any others fluid.
A quadrilateral is a polygon ("many angled") with 4 sides that intersect. Since a circle doesn't have any sides, it cannot be a polygon. A square, a trapezoid, a parallellogram, a rhombus, or a rectangle would all be examples of shapes that ARE polygons.
A rainbow is an example of an arc shape, as is any object or drawing that has a curve conforming to a section of the the circumference of a circle.
limiting friction will slow an object more than any other type of friction
