how is gravity created on earth
On Earth, gravity gives weight to physical objects and causes the ocean tides. The force of Earthâs gravity is the result of the planets mass and density â 5.97237 Ã 10 24 kg (1.31668Ã10 25 lbs) and 5.514 g/cm 3, respectively. This results in Earth having a gravitational strength of 9.8 m/sÂ² close to the surface (also known as 1 g), which naturally decreases the farther away one is from the surface. In addition, the force of gravity on Earth actually changes depending on where youâre standing on it. The first reason is because the Earth is rotating. This means that the gravity of Earth at the equator is 9.789 m/s2, while the force of gravity at the poles is 9.832 m/s2.
