Why does Earth exert a stronger gravitational force than the Moon?
Gravitational force on what?
If you are talking about an object on earth, earth is both closer and larger (has greater mass).
I hope this helps. Thanks for asking.
To understand why Earth exerts a stronger gravitational force than the Moon, we need to consider two important factors: mass and distance.
Firstly, the mass of an object determines its gravitational force. The Earth has a substantially larger mass than the Moon. Earth's mass is about 5.97 x 10^24 kilograms, while the Moon's mass is only about 7.35 x 10^22 kilograms. Since gravitational force is directly proportional to mass, a larger mass leads to a stronger gravitational force.
Secondly, the distance between two objects affects the gravitational force between them. The distance between the Earth and the Moon is roughly 384,400 kilometers. As per Newton's law of universal gravitation, the gravitational force decreases as the distance between two objects increases. So, the Moon being farther away from us compared to the Earth results in a weaker gravitational force between the Earth and the Moon.
Combining these factors, the larger mass of the Earth and the closer proximity of the Moon to Earth result in Earth exerting a stronger gravitational force than the Moon.
