Circular motion is often referred to as rotation when an object spins on its axis or revolution when an object moves around another object in a circular path.
The turning motion of an object on its axis is called rotation.
Precession. This is when the axis of rotation of a spinning object moves in a circular motion around another axis, causing a wobbling effect.
Line of symmetry
The rotational Speed or angular velocity of an object does not change even if they move away from the axis, however its linear velocity changes.
When an object moves, it uses kinetic energy.
When an object is rotated along an axis that is perpendicular to the page, it moves from being flat on the page to sticking out of the page.
The orbit is the path an object takes as it moves around another object in space, such as a planet orbiting a star. The axis, on the other hand, is an imaginary straight line around which an object rotates or spins, like the Earth spinning on its axis.
An object can move in a straight line, known as linear motion, or it can rotate around a fixed axis, known as rotational motion.
The imaginary line about which an object spins is called the axis of rotation. It is an imaginary line that passes through the center of mass of the object around which it rotates. The object rotates around this axis resulting in circular motion.
An astronomical object that moves (revolves) around a larger object is called a satellite. A natural satellite of a planet is called a moon.
It is a telescope on an equatorial drive (one axis parallel to the Earth's axis). An electric motor drives the other axis at 15 degrees per hour to follow an object as it moves across the sky.
