Flipping Physics Nice review :) So, if there's a tension force at an angle, we'd draw the tension force at an angle, rather than the force in the x and y directions?
UWBadgersfan28 Thanks! I'm not quite sure what you are asking. I have a video about understanding the Tension Force (www.flippingphysics.com/tension-force.html), but the basic gist is that the Tension Force is in the direction of the rope, wire, cable, etc.
UWBadgersfan28 Your approach to Free Body Diagrams for all the AP Physics tests should be the same. I outline the strategy in my video "5 Steps to Solve any Free Body Diagram Problem". (www.flippingphysics.com/5-steps-fbd.html) Draw the Free Body Diagram without breaking any forces into components. (This first free body diagram is an answer and shows that you understand all the forces, their directions and relative magnitudes.) Then break forces into components and re-draw the Free Body Diagram. (This second Free Body Diagram is the one you use to solve the problem via summing the forces.)
Thank you so much for making these videos, I'm sure they were very time consuming! I'm on my way to watching your whole AP Physics 1 review playlist as my exam is Tuesday! This has served as a great review tool for me. Thank you!
+allthewaystartrek You are welcome and best of luck to you on Tuesday! And yes, the videos do take quite a while to make: www.flippingphysics.com/making-a-video.html
I have a test on this tomorrow (well, today. It's after midnight) and came into this video having retained next to nothing from the last couple weeks of class. A lot of this makes more sense now so I'll let you know how that goes.
Flipping Physics the test was pushed back a day and I didn’t watch this again for some reason so I didn’t quite remember everything. Considering how little I knew beforehand, I’d say the 72 I got isn’t bad.

wait at 9:15 why is Fg2=mg*sin(theta)? When I tried doing this myself this is what I got. sin(theta)=Opp/Hyp.=mg/Fg2 therefore, when you rearrange the equation to get Fg2 by itself you should get: Fg2=mg/sin(theta) So why is mg "multiplied" by sin(theta) but not "divided" by it?
For the Ffs is less than or equal to the coefficient of static friction times Fn. shouldn't it just be less than in that equation because only the static maximum should be equal to the coefficient of static friction
Wait if static friction force is always less than or equal to coefficient of friction*normal force and kinetic force is always equal to coefficient of friction*normal force, how is static friction force always greater than kinetic friction force?
+Internet user This statement is incorrect: "static friction force [is] always greater than kinetic friction force". I would suggest you watch two of my videos. 1) Understanding the Force of Friction Equation www.flippingphysics.com/friction-equation.html 2) Experimentally Graphing the Force of Friction www.flippingphysics.com/friction-graph.html (there are more after that if you still need help.)
I have a question, as you said in the video that the frictional force always opposes motion, then what would the direction of the friction be in the case that the wheels of a car is pushing backwards on the ground? Would the frictional force face forward and help the car to move?
+Erica Hu This is a good question which I get from time to time. I should make a video of this eventually. Here goes: Picture a car accelerating to the right. Now look at where the tire meets to road. Imagine slamming on the accelerator pedal and "spinning out" the tire. Where the tire meets the road, the tire is moving to your left (or backwards) and the force of friction is to your right (or forwards). The force of friction here is opposing the leftward (or backward) motion of the tire relative to the ground. So the force of friction is to the right (or forward) and causes the car to accelerate to your right (or forward).
Bro i love the reveiws thanks for the help. I just want to say i find it funny that you have to dress up as one of the students and litteraly just stare forward while the others talk
i procrastinated a bunch and even to the point of taking the exception test, i would think i would have used the time to study but nope here i am 1 hour before :( but i'm sure your videos are good, i just don't comprehend since i'm listening at 3x speed LOL
How are inertial and gravitational mass identical if gravitational mass is inertial mass times 9.8. I'm confused, they can't be identical If one is always 9.8 times bigger (on earth) than the other.
You are confusing gravitation mass with the force of gravity. Force of gravity (or weight) equals gravitational mass times the acceleration due to gravity.
This world needs more people like you. Life saver. Truly amazed by your work.
