Question

How much would a 75kg man weigh due to the effect of gravity

Answer 1

Answer: 735 N

Explanation:

Weight $W$ is a measure of the gravitational force acting on an object and is directly proportional to the product of the mass $m$ of the body by the acceleration of gravity $g$:  

$W=m.g$

In the case of our planet Earth, the acceleration due gravity is $g=9.8 m/s^{2}$. So for a man whose mass is $m=75 kg$, his weight is:

$W=(75 kg)(9.8 m/s^{2})$

$W=735 N$
