Question

Consider an object with weight on the Earth W_earth. The gravity of the Earth is g. If it is moved to another planet with gravity a, how much will be its weight? Note: you don't need to put a number for variables, M, W, a, g

Answer 1

W_planet=(W_earth*a)/g

Step-by-step explanation:

The mass of the object does not change. It is the same at Earth and at the other planet.

W_earth=Mg weight at Earth

W_planet=Ma weight at other planet

If we divide the last equations:

W_planet/W_earth=a/g

W_planet=(W_earth*a)/g
