The moon has a weaker gravitational force than earth. Sofia weighs 50 lbs. on earth. How much will she weigh on the moon? exactly 50 lbs. less then 50 lbs. more than 50 lbs.

Question

Plz help!!!!!!!me ineed awoj uhftureh

Answer 1

Weight = mass x g. Where g = gravitational acceleration = 32.2 ft/sec2 on earth,

W denotes weight. e denotes earth. m denotes moon.

but g on the moon is 5.32 ft/sec2. So, Sofia weighs less on the moon since her mass remains the same in both places. Looking at the ratio

Wm/We = gm/ge = 5.32/32.2 = .165. So, Wm = .165(We) = .165(50) = 8.26 lbs
