Earth's acceleration of gravity

WebThe surface gravity of a planet or other body is what determines your weight by . the simple formula W = Mg where W is the weight in Newtons, M is the mass in kilograms, and g is the acceleration of gravity at the surface in meters/sec. 2 . For example, on Earth, g = 9.8 m/sec, and for a person with a mass of 64 kg, the weight In physics, gravitational acceleration is the acceleration of an object in free fall within a vacuum (and thus without experiencing drag). This is the steady gain in speed caused exclusively by the force of gravitational attraction. All bodies accelerate in vacuum at the same rate, regardless of the masses or compositions of the bodies; the measurement and analysis of these rates is known as gravimetry.

Web2) Second, you know that all objects on the Earth's surface will fall with a constant acceleration, known as g. From 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). WebAnswer: On the surface of the moon, the distance to the center of mass is the same as the radius: r = 1.74 x 10 6 m = 1 740 000 m.
