Does gravity have anything to do with real life? Yes it does.
It is one of the most fundamental experiment of macroscopic (life size) forces.
It’s how the planets move and why leaves fall,
why you can’t jump off the planet, and also
why it’s harder going uphill than down hill,
why bikes lean on a turn, why sprinklers spray far,
and why rivers run, and rain falls.
It’s why we have an atmosphere of air to breathe and
why there is less so high in the mountain.
It’s why water boil at lower temperature at high altitude and
it s why winds and clouds sometimes curl up into storms.
