Could you please explain the concept of ratios in Space questions and the example below as well Pls
For that question:
You should remember
This means the gravitational
force will be the same on both objects - Newton's third law also says "Each action has an equal and opposite reaction" which confirms this. The gravitational force on object X from Y = gravitational force on object Y from X. But, the acceleration on each will be different due to their different masses.
Note: This applies to us and the earth too. The gravitational force on us from the earth is the same as the gravitational force the earth experiences from us! But, the earth's mass is far far greater than ours so it hardly moves while we feel it quite a bit.
Ratios in space questions: could you elaborate please?
If something is in orbit, Then the gravitational force is the centripetal force so Fg = Fc
