nothing should be THAT urgent ...

What is the formula for gravitational force between to objects?

anonymous · Answer

$$f=\frac{ GMm }{ d ^{2} }$$

@amistre64

amistre64 · Answer

now take the distance and triple it; then compare the 2 results
$$f=\frac{ GMm }{ (3d) ^{2} }$$

anonymous · Answer

First thing - @basith think: does the force decay (weaken) or increase when the distance is increasing ?...

anonymous · Answer

Aand - this process is QUADRATIC. So together with first fact it yields what conclusion ?

amistre64 · Answer

$$f_1=\frac{ GMm }{ d ^{2} }\to\ f_3=\frac{1}{9}*\frac{ GMm }{ d ^{2} }$$

anonymous · Answer

$$thats,=\frac{ 1 }{ 9 }F$$

anonymous · Answer

then what?

amistre64 · Answer

then write that down and move to the next question?

amistre64 · Answer

when the distance is tripled, the force is one-ninth of what it was ...
