physics is relevant to our everyday life.
if you place two marbles on the floor some distance apart, and you roll them towards each other at high speed, they would collide, exerting a great force on each other, causing them to move apart in the opposite direction. eventually, they would slow down and end up at an equilibrium position, possibly more distant from each other than before.
however if you roll the two marbles at a slower speed, they would take a longer time to collide, (or they might not even collide) and even when they do, they merely bounce off lightly, and finally they would stop at an equilibrium position which is probably closer to each other than where they started.
people who come together too quickly, have the potential to drift apart as quickly too.
