@Nugatory Thanks for the kind help. If we apply this understanding on earth, say punching a wall, your centre of mass remains stationary until the punch reaches the wall and the reaction force pushes you backwards... and a net force is only created when you apply some of that force/momentum of...
Newton's Third Law states that forces occur in pairs of equal magnitude acting in opposite directions on opposing bodies. When we push against a wall, the wall pushes back with a force of equal magnitude and we move as a result of not being inert enough. What would the force pair be if an...
