Question

Express the law of gravitation and calculate the weight of an object.

Answer 1

if you do some calculations with Newton's Universal Law of Gravity, you come up with the acceleration due to earth being approximately equal to 9.8 m / s 2 . So, now, you can solve it (if the object is on earth). Just multiply the density by the volume, and then multiply that by 9.8, you get the Weight.
