It is approx 9.81 metres per second-squared.
Mainly gravity, and air resistance.
On the earths surface gravity pulls you down.
Yes, Earth's gravity pulls objects towards its center. The force of gravity between Earth and objects on or near its surface causes everything to be pulled towards the center of the planet.
It makes things weigh more or less, depending on the surface gravity.
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
The force of gravity on the earth is 9.8 m/s^2
All mass attracts all other mass, thats a fact. The force due to gravity between the earth and another object, is dependent on their combined mass (earth and object), and the square of the distance between the centres of gravity.
weights
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
38% on its surface.
Earth's gravity is consistent and unchanging at approximately 9.81 m/s². This gravitational force is responsible for keeping objects anchored to the Earth's surface and determining their weight.
The moon's gravity is about 1/6th of the earth's.
