1. An object in motion will remain in motion unless acted upon by a net force.
2. Force equals mass multiplied by acceleration.
3. To every action there is an equal and opposite reaction. - Wikipedia __________________________________________________ ________
This commencement of a thread on Newton’s three laws of motion (in Classical Mechanics) is to serve as a reminder of their applicability - regarding questions and answers - to contemporary issues.
Proactive Readers are encouraged to apply their recognition and consideration of these Classical-Mechanical laws as they relate - often as they interrelate in combination - to contemporary issues, problems and solutions.
One exemplary question relating to Newton’s 1st Law, is, regarding the current issue of a proposed ‘pulsating’ universe (expansion from big bang coasting to a stop and collapsation, resulting in another big bang, ad infinitum): in deep space, what resistance is there to slow the expanding universe down and eventually stop it, resulting in a collapsation? What outside force acts on the expanding (and apparently accelerating) universe to slow it down and begin the proposed ('ping pong') process of a 'pulsating universe'?
What other contemporary issues are - or appear to be - directly related to one or more of Newton’s (singularly considered or combined) three laws of motion?

(George Berkeley, 1710) ... lay the beginning in a distinct explication of what is meant by thing, reality, existence: for in vain shall we dispute concerning the real existence of things, or pretend to any knowledge thereof, so long as we have not fixed the meaning of those words.
