A circle is the form where all points have the same distance from the center.
Imagine some other form for the tyre - for example, a hexagon. To move a car (or waggon) with such tyres, the center of mass of the car would have to go up and down all the time, since in a hexagon, NOT all points are at the same distance from the center. Raising the center of mass would require a certain amount of energy; when the car falls back down (to the next side of the hexagonal wheel), part of this energy would be lost.

What is the Difference between O ring and gasket?
A gasket may or may not be circular, and it is usually flat on both sides. An O ring is always circular, and circular in girth as well.
A 200-kg car rounds a circular turn of radius 20 m If the road is flat and the coefficient of the friction between tires and road is 70 how fast can the car go without skidding?
define skidding.... 30mph.
Is angular momentum always parallel to angular acceleration?
momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel
Is genetic material circular?
Our genetic material is stored in outlet DNA, which is spiral shaped, jot necessarily circular.
What are the applications for circular linked lists?
A singly-linked circular list is useful for implementing queue data structures with minimum overhead. Normally we implement a queue with two pointers: one to the tail for insertions and one to the head for extractions. With a circular list we only need to maintain a single pointer to the tail because the tail always points "forwards" to the head (instead of null as it normally would), thus achieving constant-time access to both the head and tail via a single pointer. Circular linked lists are generally useful wherever "wraparound" is necessary. That is, from any given node in the list, we can traverse forwards with the guarantee that we will eventually arrive back at that same node. With doubly-linked circular lists we have the advantage of traversing in either direction (bi-directional traversal).
Why are tires made circular?
to reduce friction tyres are made circular
Does ringworm always have to appear in a circular shape?
No, ringworm does not always have to appear in a circular shape. It can present in various shapes and sizes on the skin.
For an object moving in a circular path which quantity is always changing?
The direction of the object's velocity is always changing as it moves in a circular path.
Is ringworm always circular in shape?
No, ringworm is not always circular in shape. It can appear as a red, scaly patch on the skin that may be round or irregular in shape.
How centripetal force is acted on a car moving in a circular motion?
To curve in a circle, the car's tires push outside against the road; the road pushes inward against the car's tires.
What force is always perpendicular to the motion when in a circular motion?
The centripetal force is always perpendicular to the motion in circular motion. It acts towards the center of the circle, keeping the object moving in a circular path.
When did cars start having rubber tires?
Since cars were first made tires were always rubber.
Are tires sold as pairs or singles?
tires are sold in singles. but you can always buy more than one if needed.
What is the Difference between O ring and gasket?
A gasket may or may not be circular, and it is usually flat on both sides. An O ring is always circular, and circular in girth as well.
For an object moving in a circular path which quanity is always charging?
The direction of its velocity is always changing.
In circular motion the what force is always perpendicular to the motion?
The Centripetal Force
When an object moves around the circular track the centripetal force is provided by?
In an automobile, the friction force of the tires allows the vehicle to follow a circular course, because the friction, or grip, of the tires resists the sideways, or outward force known as centrifugal force. In free space, an orbiting body has gravity acting to provide the centripedal force.
