Assuming you weigh 165 pounds and the distance between you and the center of the earth is 6,400 km. If the mass of the earth is 6.0x10^24kg and G=6.67x10^-11

Question

What is the gravitational force between you and the earth?

Answer 1

The given weight of 165 pounds is the gravitational force between you and the earth.  I assume what you want is the force calculated using Newton's law of gravitation, in Newtons.

 

Convert to kg:

 

A weight of 165 pounds contains 165*0.454 kg = 74.91 kg

 

F = GmM / R² = (6.67 x 10^-11 N m²/kg²)(74.91 kg)(6.0 x 10²⁴ kg) / (6400 x 10³ m)²

 

F = 731.9 N
