Gravity is the force that pulls objects toward each other, especially the pull that makes things fall to the ground and keeps planets in orbit. It also can mean seriousness or importance in behavior or situations.
“Gravity” comes from Latin “gravitas,” meaning heaviness or seriousness. Scientists adopted the word to describe the force related to mass and weight.
You feel gravity constantly, but you never see it—only its effects, like falling objects and orbits. In space, astronauts still experience gravity; they seem weightless because they are falling around Earth, not away from it.
