Answer:
Weight is the force exerted by a mass under the influence of gravity. (w = m*g).
Weighing scales calibrated for the earth would show that…
490N = m(kg) * 9.8(m/s^2) => m = 490/9.8 = 50kg.
On the moon the same scales would give his weight as 50 * 1.62 = 81N.
Has he lost mass? No!
His mass is being subjected to less gravitational acceleration, he feels lighter.
