How does gravity work on Earth and what are its effects on objects and phenomena?

Oh darling, gravity on Earth is what keeps us grounded and saves us from floating off into space. It pulls everything with mass towards the center of the planet, thank goodness for that or we'd all be in a real pickle. So, buckle up and enjoy the ride called Newtonian gravitation, it's a bumpy one but hey, at least we're not floating around like lost balloons.
