Answer :
An object's weight is
(its mass) x (the acceleration of gravity wherever the object is) .
The acceleration of gravity on or near the Earth's surface is about 9.8m/s².
So an object with 10kg of mass, as long as it's located on or near the
Earth's surface, weighs
(10 kg) x (9.8 m/s²) = 98 kg-m/s² = 98 Newtons.
That's about 22.05 pounds.
If you take the object somewhere else, it's still 10 kg of mass, but
it weighs something different, depending on the gravity of the place
where you take it.
