Hi, I am confused over the potential energy equation. I have been taught that potential energy is MGH M=mass, G=gravity on surface, and H=height from earth. However being on the internet and learning more i have noticed people use GmM/r^2 and i am very confused why it is switched. please help me...
I am from New York, and a physics student. ( not trying to give to much info on the internet.) but i was curious in why people on the internet use PE equation as GmM/r^2 when i was taught that it was PE=MGH? please help me with me confusion? thank you.
