Phrases with «surface gravity»

"Surface gravity" refers to the force or pull of gravity experienced on the surface of an object, like a planet or a star. It indicates how strong gravity is at that specific location. For example, the surface gravity on Earth keeps us firmly planted on the ground, while the surface gravity on the Moon is weaker, allowing astronauts to jump higher. So, surface gravity tells us how much gravity is felt on the surface of an object. Full definition
