Physics Mid term Monday

So hey guys I have my physics mid term on Monday and I'm hopeless. I'm not sure what to study because I'm not sure whats important so I was wondering what are some important things and concepts in physics? Also are there any websites that are very useful? Thanks Basil!

Energy cannot be created or destroyed.

@sufferable ooh ok I get it. Don't know the answer but I understand what you mean lmao

[quote=Lightning715]@Sufferable Ok thanks! This is actually really helpful so I'll do that process on the exam and seems like you're learning a lot of the stuff I am learning. Except for conceptual questions because idk what that is or means lmao[/quote]

Conceptual questions don't require work though it most of the time requires the use of an equation. It's like if the force goes up what happens to the acceleration (stupid question but you get the point).

All I can say is know your equations. My midterm had some problems dealing with interpreting different graphs (velocity vs. time, etc), applying kinematic equations (projectile). blocks on an incline plane in a will it move type problem, as well as some conceptual questions which imo are the hardest. Save all the problems that require written out work until the end. If you are stuck on problems that you have to show work on then apply all the formulas you can think of and see if you have all the relevant information to apply these formulas. Though it varies between physics classrooms as even the 2 different physics teachers in my school taught 2 different physics topics.

@twilightpho Yeah ik a good bit of the formulas, but I don't really understand like the process of using them... For example, I can probably solve a problem about a pulley system with a hanging weight of 5 KG and with the other weight with a weight of 6 KG and solve for the force of friction. But if it gave you the force of friction instead and had you solve for something else like how much the hanging weight weighs I wouldn't be able to solve for it you know what I mean? Idk I have trouble adjusting to the situation in the problem
@soulblade Never clicked on the link till now and just realized that it was an anime website haha

Well, I'd start off by making sure you understand forces and how to calculate with with vectors. Since you don't really have much time, memorize all the formulas and what the variables stand for. If you have the formulas memorized, you should be able to solve most of the problems =~=

Midterm? The semester hasn't even started yet!

@jhwan Ok thanks! Yeah my study guide from our school sucks -_-

PM me for some study guides. I took freshmen level physics two years ago, and my study guides might help.

@FireBreather I have but my teacher is literally one of the worst teachers I have ever had. I come in the morning for help and he's never there.
@SoulBlade @Darkwolf6545 thanks so much! And yeah I'm in ninth grade I didn't learn that bottom half of the things you listed but its ok. Hopefully I can get a good grade
@AveryMBII Ok thanks for the advice!

It's a midterm, so cover everything you've done for the previous term(s).

I'm in Physics too, Grade 11 This is what I have to study, I hope it helps you.

uhhh

Kinematics
5 equations of motion
graph conversions

Dynamics
gravity is proportional to mass and distance of the two objects
force = mass * acceleration
force of gravity = mass * gravity
friction stuff
Newton's laws (inertia, mass*acceleration, action-reaction)

Mechanical energy
kinetic energy = (mass * velocity^2)/2
gravitational potential = force of gravity * change in height
power stuff (watts and efficiency)

Thermal energy
change in thermal energy = mass * specific heat capacity * change in temperature
latent heat of fusion/vaporisation

stupid nuclear energy stuff

stupid waves stuff

electricity and magnetism stuff

e=mc^2
velocity is the derivative of position
acceleration is the derivative of velocity

Me too And I always procrastinate really badly so I probably won't start studying for any of my finals until like mid-day tomorrow. Luckily I've gotten pretty good at this so I'll still do alright on it.

Just go through the concept and practice it or study it till you understand them. Physics is one of those things that I could barely understand. It helps that my dad has a physics major and that my final was composed only of questions from past quizzes. I think I got a low B in that class.

every chapter is important in physics bro... you can't cramp this subject lol im sorry don't know what to tell you
that reminds me i should study for my wave test
