Question

a person weighs 70 kg on earth where g is constant what is his mass ?​

Answer 1

Let us perform a simple calculation. We will calculate the gravitational force on a 70 kg astronaut while in the ISS. On Earth, a 70 kg person weighs 706 Newtons (or 160 lbs).

Answer 2

Explanation:

70kg person would weigh 686N (70kg x 9.8 ) whereas on the moon, where the gravitational acceleration is about 1.62 , that same 70kg person would weigh 113N. This means on a pair of scales calibrated for earth they would measure 11.5kg. G-force is another name for the acceleration due to gravity
