rotation
An orbit. In fact, orbits are not usually exactly circular. They are "elliptical".
A force that acts on a body moving in a circular path and is directed around the object which the body is moving
one complete circular movement made by one object around another object
Centripetal force is necessary to keep an object in a circular path.
It is the distance around an outside of a round 180 circular object
The answer will depend on what the 12 mm measures. If the object is 12 mm in diameter, it is 37.7 mm around.
An orbit can be referred to as a noun or verb. As a noun, it refers precisely to the elliptical or circular path one body has around another. As a verb, it means to move or travel around in an elliptical. But in general it is a repetitive and routine pattern that one object takes around another. An object involved in an orbit is called a satellite. The position of the object can be determined at any given time, unlike an object in an orbital (impossible to determine the exact location, like with electrons around the nucleus). This object can be natural like the moon, man-made, or extraterrestrial. In our solar system the 8 planets revolve around the sun in an elliptical or circular shape. Some of these planets have moons which orbit around them.
to take a circular path around an object
A rotation is a movement of an object in a circular motion. A two-dimensional object rotates around a center (or point) of rotation. A three-dimensional object rotates around a line called an axis.
circular
When an object is moving in a uniform circular motion while traveling in a circular path, this means it has a constant speed. When an object is moving in a circular path, this indicates it is constantly being pulled towards the center of the circle.
