The star's movement in space can be separated into two components. Observation for the two components differs drastically.
explain motion?
retrograde motion
to explain the motion of planets, especially the phenomenon of retrograde motion where planets appear to temporarily reverse their direction of motion. Ref: Andrew Liddle "An Introduction to modern Cosmology".
Where no matter exists, there is nothing to interfere with the rocket's motion through space. A body in motion tends to remain in motion, and if nothing interferes with that motion, the body will continue to move.
For every action there is an equal and opposite reaction, the force of the rocket's output translates to the forward motion of the rocket.
Print engine: accepts data and commands, and translates them into motion.
Newtons 1st law, "An object in motion will stay in motion unless acted upon by another force." Basicly the photons travel through space gradually spreading out as they hit different particles.
It helped them explain and describe motion
Newton's F=ma is an example of a law that could explain all motion in the universe.
Earths faster motion makes Mars appear to be going backwards, the backwards motion, in fact, is what caused retrograde motion. --Ptloemy used Epicycles to explain how geocentrical models worked.
Viscosity opposes the motion of an object through liquid.
