Physics help -Effective weight?

Question

can someone explain it to me(brief)

THanks dr :o)

Answer 1

Simply put, your Mass is always your mass - no matter what planet or galaxy you go to.

Weigth is defined as-:

Mass x Acceleration due to gravity

Therefore on planet Earth you are (say 65kg mass)-:

65 x 9.81 = 637.65 Newtons

But if you were to go to the moon-: (your mass is still 65kg) BUT-:

The moon is only a 1/6 of the Earths gravity, so -:

65 x (9.81/6) = 106.275 Newtons.

Your weight is the Force you exert on the surface you are stood/lying/sat upon.

Hope this explains it better. Dr.Q ;o)
