Your shoulder, your hip joints.

Joints\n\nA joint, or articulation, is the place where two bones come together. There are three types of joints classified by the amount of movement they allow: immovable, slightly movable, and freely movable.\n\nImmovable joints are synarthroses. In this type of joint, the bones are in very close contact and are separated only by a thin layer of fibrous connective tissue. An example of a synarthrosis is the suture in the skull between skull bones.\n\nSlightly movable joints are called amphiarthroses. This type of joint is characterized by bones that are connected by hyaline cartilage (fibro cartilage). The ribs that connect to the sternum are an example of an amphiarthrosis joint.\n\nMost of the joints in the adult human body are freely movable joints. This type of joint is called a diarthrosis joint. There are six types of diarthroses joints. These are:\n\nBall-and-Socket: The ball-shaped end of one bone fits into a cup shaped socket on the other bone allowing the widest range of motion including rotation. Examples include the shoulder and hip.\n\nCondyloid: Oval shaped condyle fits into elliptical cavity of another allowing angular motion but not rotation. This occurs between the metacarpals (bones in the palm of the hand) and phalanges (fingers) and between the metatarsals (foot bones excluding heel) and phalanges (toes).\n\nSaddle: This type of joint occurs when the touching surfaces of two bones have both concave and convex regions with the shapes of the two bones complementing one other and allowing a wide range of movement. The only saddle joint in the body is in the thumb.\n\nPivot: Rounded or conical surfaces of one bone fit into a ring of one or tendon allowing rotation. An example is the joint between the axis and atlas in the neck.\n\nHinge: A convex projection on one bone fits into a concave depression in another permitting only flexion and extension as in the elbow and knee joints.\n\nGliding: Flat or slightly flat surfaces move against each other allowing sliding or twisting without any circular movement. This happens in the carpals in the wrist and the tarsals in the ankle. \n\nP.S.  does this help you?

A two piece ball like Pinnacle will go the distance.  Balls that spin will not go as far

Here is one example...the bouncing ball. Just google that in and you get a bunch of results.

What is your question?  joints provide the ability to move.  What are you asking?

I'm not sure to what extend should I answer this. But just what I have in mind and I think might be related. \n-The molecules within the ball are closely packed together (they interact with one another) ; and this what gives solid their firm/fixed shape.\n-The energy of the molecules is low compared to energy of molecules of liquid or gas.The molecules basically stay fixed on their position and vibrate with minimum amplitude.\n\nThat's mostly about physics for ball. I'll add more if I remember more. Cheers

it is when ur thumb goes out of the socket that connects your thumb to ur ligament or socket in you carpel.

We have different joint types. Among these are ball and socket joint ex. shoulders and hips hinge joint ex. knee etc. Also, we can classify them as synovial joints, cartilaginous etc.

here a couple of examples.

Sealing member for a spigot and socket coupling, comprising a retaining part, a sealing part extending with two steps within the space bound by the inner circumference of the retaining part and of the extension thereof and a connecting part interconnecting the retaining part and the sealing sleeve. At any point between the junction with the retaining part and the free end of the sealing sleeve, the thickness of the sealing member is not greater than the thickness of the part extending between said point and said junction. The thickness does not exceed the thickness of the sealing member at said junction. The inner side of the steps of the sealing member are provided with leakage-preventing ribs and the retaining part is substantially perpendicular to the connecting part, whilst the first step of the sealing sleeve is situated within the inner side of the retaining part. The end of the sleeve is provided with a tapered lip forming preferably a sort of sickle with the sealing member. - I hope that is clear!!!
