Document Summary
Mass: property that determines an object"s resistance to acceleration by forces and the strength of its mutual gravitational attraction to other objects. Weight: the force on an object due to gravity. W = mg = mgm/r^2 g = gm/r^2 g = 9. 8m/s^2 on the surface of earth. A mass of 70 kg corresponds to a weight of 154 lbs on earth, 140 lbs on mars 58 lbs on the moon. Gravitational force is often expressed relative to earth"s. The earth has an equatorial bulge due to rotation g = gm/r^2 g = 9. 78 m/s^2 at the equator (9. 83m/s^2 at the poles) To a widowed mother who later remarried after isaac was born. Raised by his maternal grandmother instead of mother/stepdad. Grew up a solitary child, but was unfit to be a farmer. The rural setting of his childhood likely played a large role in this ability to stick to himself. As an adult isaac was quiet, irascible, and solitary.
