Hm..
I am still very confused. When using the Universal Law.. I understand that Fg in the law is what I need to find.. and I also understand that if you graph what I'm looking for, you would get an inverse.. But after that.. I'm really lost.
would it be something like: y = G * 1/(r+x)^2...
I really really need help with his..
How can I make a formula that will give me the force of gravity at different elevations? Like.. x would be elevation and the y would be the force of gravity. I know I have to use Newton's law of Univerisal gravitation and sutff, but I don't know where to...
Having trouble with this question:
"Friction provides the force needed for a car to travel around a flat, circular trace track. What is the maximum speed at which a car can safely travel if the radius of the track is 80.0m and the coefficient of friction is 0.40?"
Any help would be great.
