If Earth suddenly lost all of its gravity, we wouldn't just start floating. The lack of any forceful gravitational pull would turn humans and anything else with mass, like cars and buildings into very fast-moving tumbleweeds. If there was no gravity on Earth, everything would float away into space, including people, animals, and objects. This is because gravity is what holds objects with mass to the surface of the planet. Without gravity, there would be no force keeping us or anything else on Earth. Mount Nevado Huascarán in Peru has the lowest gravitational acceleration, at 9.7639 m/s2, while the highest is at the surface of the Arctic Ocean, at 9.8337 m/s2. “Nevado was a bit surprising because it is about 1000 kilometres south of the equator.
