IB Physics Topic 6, Circular Motion and Gravitation SL Paper Questions

Disclaimer: For the problem at 15:54, the correct answer is A(0.1) instead of D(10). I calculated the correct answer but circled the wrong option.
For problems at 50:36, the correct answer is D. Net force in the direction of motion is zero since the object is in uniform circular motion, meaning that there is no acceleration in the tangible direction, so net force is zero. In the direction normal (perpendicular) to the direction of motion, it receives a centripetal force, so net force is a non-zero quantity.

Thank you so much!! Your video helps me to study for my test and I like how you explain the process for every questions 😊

Thank you very much, but out of curiosity did you finish this year’s Physics IB? If yes, then make a video for tips. Thus, can you add paper 2 please ( the same as this video’s length it’s no problem)

I got √2T on page 7. Cuz I got Tsquare = 2 so T=√2
