WebAt Earth ’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 … A non-rotating perfect sphere of uniform mass density, or whose density varies solely with distance from the centre (spherical symmetry), would produce a gravitational field of uniform magnitude at all points on its surface. The Earth is rotating and is also not spherically symmetric; rather, it is slightly flatter at the poles while bulging at the Equator: an oblate spheroid. There are consequentl…
WebFrom Newton's second law of motion, F=ma, you get that mg=GmM/R^2, where M is the Earth's mass and R is the Earth's radius. Do a little algebra, and you get that M=gR^2/G. g is measured, and so is R. All you need is G (and love). WebYes. There's gravity everywhere - it's an intrinsic property of all matter that has non-zero mass. If you were at the centre of the Earth it would feel like you were weightless. This is …

Weight is the total force acting on an object due to the gravitational force exerted by an astronomical body. This means that the center of gravity is the point in an object or system where the average of all the weight lies.
