I don't believe there is one. I tried just simple math but it seems to good to be true.

doesnt r stand for the distance or radious?

yes

i spoke to my proffesor about it but all he said was to put 1 in m1 and m2... for r^2 since it says to quadruple to just put 4^2 I asked about the G in the equation but he said not to worry about iit and pretend its not there...

i was reffering to the question i had just asked, not the OG

but it said "IF"

example "Free fall v=vi+at, a= -10 m/s2 , if up is chosen as positive direction of axis" does that mean if the quesyion is saying downward or upward use -10 or +10 ?

one more question. when the problem given gives you "a= −10 m/s2" instead of " a= 10 m/s2" the difference is just plugging the number in as a negative ? i know the negative is just direction but as far as putting into an equation it'll be negative ?

great :') you have been very helpful! thank ypu sooooooooooo much

how come both answers are postive when one is upward and the other is negative on the websites hw? what youre saying totally makes sense

so when using g = 10 m/s2 the 10 would always be negative ? or depends on the direction its going ? the second part of that question is t=2 my answer ended up being negative but the correct answer is positive

can you explain why they are using g = -10 m/s2 when they are saying its g = 10 m/s2 ?

with this specific question, its asking for the The magnitude of the velocity which in other words makes me believe that its not just asking for velocity but for something else. as well as g+10m/s^2 also being the same thing as acceleration in some formulas like Vf=Vi +at

i just did a two chapters on average speed, distance, instanteneous speed, motion etc etc and i was able to understand the question asked and know whixh formula to use. for some reason something is just not clicking for this chapter, there are a few different words used to describe thesame thing...
