Example: Moon revolving around the sun (although it's technically elliptical not perfectly circular)
-speed is constant but velocity changes constantly since the vector changes direction but not magnitude.
Concentric reducers are a symmetrical, conical shaped device that enlarges or reduces a pipes diameter equally about the centerline. An Eccentric reducer is not Symmetrical about the centerline. For example, envision the flow through a gravity based pipe... picture it in terms of an elevation section view... the eccentric reducer maintains the flowline (a straight continuous line along the bottom) while the pipe size decreases from the top down.
A cam is a rotating component used in a mechanism in order to transform a movement from a circular to a reciprocating motion. A crank performs the opposite action. A common example of a cam mechanism is that found on a car engine where the camshaft translates the rotary motion of the engine into a reciprocating motion to operate the intake and exhaust valves on the engine cylinders. Please see the related links for an example animation and more detailed explanation.
The pump discharge reducer doesn't matter if it's concentric or eccentric. It's the pump SUCTION that needs to be an eccentric reducer that is always flat on top (F.O.T.) The eccentric reducer on the pump suction reduces pump cavatation (pump catching air).
Whitworth quick return mechanism is a device where reciprocation motion in forward stroke is slower then the return stroke.
For flexibility or movement. For example most of our bodies joints have a mechanical disadvantage for the simple reason we gain range of motion and flexibility.

No, a cricket bowl is not a concentric contraction. A concentric contraction occurs when a muscle shortens while generating force, such as when lifting a weight. In cricket, a bowl refers to the action of the bowler delivering the ball to the batsman. This motion involves a combination of eccentric and concentric muscle contractions.

No, Newton did not describe the universe as a series of concentric spheres. He is well known for his law of universal gravitation and his laws of motion, which laid the foundation for classical mechanics. Newton's ideas were more focused on explaining the motion of objects and the interactions between them rather than describing the universe as concentric spheres.
Newton's ideas did not describe the universe as a series of concentric spheres. He is more famously known for his laws of motion and universal gravitation.

No, Newton did not describe the universe as a series of concentric spheres. He is best known for his work in physics, particularly his laws of motion and law of universal gravitation.
An example of a concentric exercise is a bicep curl, where you lift a weight towards your shoulder. This exercise benefits the muscles by primarily targeting the bicep muscle, helping to strengthen and tone it.
An example of a Roundel is a circular concentric design of National colours on the wing of a military aeroplane.
Eudoxus of Cnidus, a student of Plato, developed the system of concentric spheres in his attempt to explain planetary motion and the movements of the stars. This system later influenced the Ptolemaic astronomical model, which incorporated epicycles to account for observed planetary motion.
