Question

Define the following words: axis, rotation, orbit,dusk.​

Answer 1

axis - an imaginary line about which a body rotates.

"the Earth revolves on its axis once every 24 hours"

rotation - Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point. In three-dimensional shapes, the objects can be rotated about an infinite number of imaginary lines known as rotational axes.

• in physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to non-repeating trajectory.
