I just started taking physics this year (junior year in high school) and I can honestly say that I have no idea what's going on. Alright, so I know about free fall (well...the falling part of free fall, not when the ball bounces up and back down again) and acceleration, but pretty much anything other than stuff that's clearly cut I have no idea where to even START. One problem is:
As a large jet flies at a constant altitude, its engines produce a forward thrust of 8.4 x 10 ^5 N. The mass of the plane is 2.6 x 1^5 kg.
a. What is the forward acceleration of the plane, ignoring air resistance?
b. How much upward force must the air exert on the plane when it is flying horizontally?
And is there a site or something that I can learn forces from? I don't know which forces are opposites (like one is positive and one is negative) and which forces are completely the same and balance each other out.
