The gravitational force on the moon is less than on Earth because the strength of gravity is determined by an object’s mass. The bigger the object, the bigger the gravitational force.

Standing on Earth's surface, the planet's mass creates a gravitational force sufficient to accelerate any object downward (toward the core of the planet, or perpendicular to the planet's surface ...

Gravity — that invisible force that draws objects to the center of the Earth — is not uniform across the planet, data shows.

In this excerpt from "CHARGE: Why Does Gravity Rule?", theoretical physicist Frank Close explains the most tangible fundamental forces — magnetism.

Every planet in the solar system is affected by multiple forces. The gravity of the Sun pulls planets toward the center of the solar system. The inertia from the creation of the planets sent them ...

Because the force of gravity is stronger at shorter distances, the early Earth-Moon system experienced enormous gravitational tidal forces compared to today’s more distant pairing.

When Earth rotates as normal, the centripetal acceleration of the ground under your feet at the equator has the net effect of reducing the force of gravity on you, so you weigh about 0.3 per cent ...
