1. The problem statement, all variables and given/known data How do I write equations on a computer? I need some help with some Physics equations. I am about to take a course. I have very poor math skills, so I am hoping to improve my confidence, while learning some interesting equations. I have included Boyles Law as it is the Boyle Law equation that helped me realise that I am missing something. I have studied Earth Science so far. I start chemistry/Physics next Trimester. 2. Relevant equations My first question regards the equation: p = po + pgh p = Pressure o = angle (I think) h = height (I think) I don't know what the g stands for. I infer that the equation is saying: pressure = pressure x angle + pressure x g x height This makes no sense to me The other question regards the following pV = K1. This is known as Boyles law. It explains the behavior of gas. I understand Boyles Law, but not why it is expressed with that equation. If I were to read that equation without knowing anything about Boyles Law I would read it as the following: 3. The attempt at a solution Assume p (pressure) = 5pa and V (volume) = 4m3. K1 = Constant 5 x 4 = Constant (it actually equals 20?!) Which in my view makes no sense. I learnt at high school if two letters are beside each other with no symbol, than you multiply them. Perhaps i'm mistaken?
