Question

On Earth, how many grams of mass does it take to produce a force of 1 newton?

Answer 1

The weight of an object of mass m is equal to:

`W=mg`
where
`g=9.81 m/s^2` is the gravitational acceleration.

If we require a mass m to produce a force of 1 N, it means its weight is 1 N. Therefore, the required mass is:

`m= (W)/(g)= (1N)/(9.81 m/s^2)=0.10 kg`
