Hi Andy! Your level of teaching is superb! I, in all honesty, learn the most from YOU! One thing, though: I believe the answer to a_c (time stamp: 13:48), is supposed to be 5.94E-1 m/s^2, or 0.594 m/s^2, assuming all previous answers to be correct, would it not? I calculated it twice, once on my calculator, and once again on Desmos, and both gave me the answer of 0.593609625668. Would you wanna quickly double check? Other than that super minor thing, I cannot thank you enough for posting these lessons for all of us to learn from. You are single-handedly getting us through our physics classes. Best, Rina

Your video is so great. I am in the middle of my May Physics Sl exam. I am sad for finding your channel late but also happy for finding it before my final exam. You explain it so well (much better than my teacher). I am pretty sure all your student get a level 7. Just wonder do you have some IA topic recommandation material that could be shared if you still have it (I know you have left teaching). Thank you for the great content.
@AndyMasley Жыл бұрын
My advice for the IA: 1: A good IA is often a middle school-level experiment with high school-level analysis. You don't need to do something crazy, just a simple experiment with a clear independent and dependent variable and a pattern that's either linear or that you can linearize. 2: It's often helpful to look through the IB physics equations and find one that has two variables that you can test. As a very simple example, you could look at F = ma and measure how the acceleration changes when the same force is applied to different masses and rearrange the equation to be a = F(1/m) where a is the dependent and m is the independent variable. Working backwards like this from an equation to an experiment can make it easier to find something you can linearize and analyze in the data analysis section.
@jamesluc6506 Жыл бұрын
@@AndyMasley Thank you so much for your helpful suggestion. I have another quick question, who will mark our IA? I have heard two statement where one says that the teacher marks your IA and one or two IA of your class will be sent to IB to be reviewed and they will decide to increase/decrease the mark of the IA marked by your teacher. And another one states that the teacher only gives you the predicted mark, the IB will review and gives you the final mark. The reason I asked it is because our teacher clearly tells us if we choose a SL topic, is it at most about level 5 and he always suggest us to choose hl topic ot outside the syllabus of IB, so I am concerned if he will be the person to give us the final mark for IA. Thank you very much!

Great video, but I have a question regarding the Example Problem 1! The formula booklet stated that a = v^2/r = (4 x π^2 x r)/T^2, and in the video you used v^2/r to get a = 4.641. But technically, in the given variables, you already have r and T, so would it not be easier if you just substitute everything inside (4 x π^2 x r)/T^2? That is what I did, however I ended up having a = 4.626 instead. Could you help me verify what went wrong? Because essentially they should be giving the same answer.
@AndyMasley Жыл бұрын
You're correct that those formulas are equivalent to each other. Ultimately physics has many formulas that can be rewritten based on convenience. F = ma could also be F = m(Vf -Vi/t) if the variables called for it. Our answers are so close that it's possible that I just rounded incorrectly!

I have a very simple but question. Why doesnt the object collapse into the point. Since the centripetal force is an acceleration is increasing with time it should get to a point where its high enough to pull the object towards its centre. For example: The electron in an atom if not for its stationary state it should be pulled towards the nucleus since the proton and nucleus attract but what keeps it moving in a circular path is the fact that they have fixed energy called stationary States so they can't lose energy. But objects in the real world dont have fixed energy level so what keeps them in circular path? Another example is that if we change the mechanics occurring on the body interms of force, The centripetal force will be the F=m×a but converting the objects tangential velocity into force its F=0 since it has no acceleration.Resolving the 2 forces the object is supposed to move towards the center so why does it still move circular

Which was giving me the answer of 29,806 m/s. However you got the answer of 2.98 x 10^5 which is 298,000 m/s. I just wanted to ask if I went wrong in the calculations anywhere or was the displayed answer a typo? Thanks again.

@AndyMasley2 жыл бұрын
Correct! It's actually an almost-perfect circle, the ellipse is usually exaggerated in diagrams, but it's technically not uniform circular motion. I find it has enough of the same properties as uniform circular motion (centripetal force and tangential velocity) that it's a useful example to explain UCM, but it's technically not perfectly uniform.

If accelration and deceleration can be felt or sensed, how come then, we dont feel or detect the earth spinning 1600+ km? Or dont feel it as it makes a decelration and acceleration while making its eliptical orbit around the sun at nearly 70,000mph nor feel or sence anything as it orbits the center of the milkyway galaxy at one half million miles an hour? Earth is spinning on its axis at high speeds while obiting the sun at high speeds while its also orbiting the galaxy at even more fantastic speeds and we as individuals standing(sitting lying down) on earth cant detect any of these things Despite the fact that spinning in a circle is acceleration with is detectable and "felt" while earth is also accelerating and decelerating in the eliptical orbit (deceleration is also detectable and/or felt) arpund the sun and in addition to that orbiting the milkyway at a half million miles per hour? There are numerous spinning motions and orbiting motions happening (both of which we are told are " felt" and or detecatble at fantasitc speeds). Yet according to a einstein who was quoted Saying that he has "come to the conclusion that the motion of the earth cannot be detected".
@AndyMasley3 жыл бұрын
Acceleration can only be detected when we experience some resistance to it. Astronauts on the International Space Station float freely, but they're constantly accelerating toward the Earth. They don't feel it because everything around them is accelerating at the same rate. Similarly, we don't experience Earth's rotation because everything around us is rotating with it. This video goes into the details of how the experience of acceleration is related to Einstein's theory kzbin.info/www/bejne/joPVYp6XjbB1qbc
