As the most familiar physical force in the universe, gravity may not seem exciting, but British science writer Clegg (Armageddon Science) shows how this “omnipresent” force—which strengthens bones and ...
Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and theoretical physicists, it is also a vexing invisible architect that ...
Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold new line of research now argues that gravity is not fundamental at all, ...
GRAVITY is supposed to be reliable. It’s the familiar force that keeps our feet on the ground and Earth’s atmosphere from hurtling into space. On grander scales, it has shaped the evolution of the ...
Astronomy: Ask Astro: If gravity is the weakest fundamental force, why is the Sun’s gravity so far-reaching?

Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth.
GRAVITATIONAL PULL See Gravity GRAVITY The force of attraction between two objects which is influenced by the mass of the two objects and the distance between the two objects. GYROSCOPE A heavy wheel or disk mounted so that its axis can turn freely in one or more directions. A spinning gyroscope tends to resist change in the direction of its axis.
