What is the weight of a 68-kg astronaut (a) on earth, (b) on the moon (g = 1.7 m/s2 ), (c) on mars (g = 3.7 m/s2 ), (d) in outer space traveling with constant velocity?

Solution:-
the actual weight of a astronaut( m) = 68-kg.
formula of waight (W)= gravity(g)×mass(M)
●case1 - on the earth
9.8×68 = 666.4 = 6.7×10^2newton.
● case2 - on the moon
1.7× 68 = 115.6 =1.6×10^2 newton.
● case3 = on the mars
3.7× 68 = 251.6 = 2.6×10^2 newton
● case4 = in outer space
In outer space with no gravity
there is no weight and the answer is 0 newton.
● The key is constant velocity which means zero acceleration due to gravity.
