I got an A on my test. Thank you all!

ahhh... i think that's what i need... i'll let you know how my test today goes :) (that was just the way of saying it that made it click in my head)

Lets say there is a massless string hanging from the ceiling and on the end is a 1kg mass. The tension would be 9.8 N, right? What if the string goes over a pulley, and on the other side is a 2 kg mass? The system would accelerate. What would the tension of the string be?

Yeah, I get that part. So i guess the question is, how do I calculate the tension?

I have a hard time conceptualizing string tension, and hence calculating it. For a hypothetical situation, there is a massless string connecting two blocks on a flat, frictionless surface. Block A is 5 kg, block B is 3 kg. There is a string attached to the outside of Block A, and a force of...
