How does gravity work on Earth?

Transcript

Gravity on Earth is the force that pulls objects toward its center, giving them weight. It is a universal force acting between all bodies with mass, as described by Isaac Newton's law of universal gravitation, which states that the force depends on the masses of the objects involved and the distance between them. Near Earth's surface, the acceleration due to gravity is approximately 9.8 m/s², causing freely falling objects to increase in speed. Variations in gravity exist due to factors like altitude and the Earth's rotation.

It is a universal force acting between all bodies with mass, as described by Isaac Newton's law of universal gravitation, which states that the force depends on the masses of the objects involved and the distance between them[1][5]. Near Earth's surface, the acceleration due to gravity is approximately 9.8 m/s², causing freely falling objects to increase in speed[2][3][5].
