    Where is the center of the wing's turn? Is it relative to an observer on the earth (ground) or is it somewhere else above the wing somewhere in space? Does the total lift vector (moment) point to the center of the turn or does the horizontal vector (moment) determine where the center of the turn is? If it is not with respect to an observer on the ground, then the center of turn is not pointed by the horizontal lift vector. If this is so, both wingtips have no relationship to the ground and thus, both wingtips are flying at the exact same airspeed, with respect to the airmass, right? Wrong?

    this video is up to the mark. honsetly. but I got confused on the deflection of alpha and beta in the electric field as my book (Cambridge olevel by Heather...) represents alpha deflecting more than beta in the electric field which is totally against your provided lesson. can you help me out with some valid resources?i really depend on your quick response as your answer means a lot to me, my exams are at the top of my head. kindly answer me as soon as possible and thank you for such content .it really helped me a lot.

    • @ajsenju9383
      @ajsenju9383 4 หลายเดือนก่อน

      particles are accelerated due to weak nuclear force,so electrically charged forces of the electrodes oppose that vector, alpha is a general forceful emission but beta on the other hand a decomposition of neutron,similar velocity but alpha has much mote force(Newton's laws), so it would take more work,ie,more distance to express its force(w=fscosQ),and hence less deflection of a particle

      5:11 the F is not going clockwise it is a anticlockwise moment if you look closely you will see the 80N is going the same direction as F.

    Hi Mr Lovatt! I'm Dang from Y10 in BIS. You've taught me physics a while back. I'm in college rn study about computers but I'm still heading back here to learn Physics for a bit of fun ^^. I'm glad to be able to revisit these wonderful videos. Hope you are doing well & you'll continue to make these videos for your future students. (P.S This is the video that actually saved me my IB Higher Level physics during my year 13 so thank you for that xD)

    Thank you for your kindness to explain all the rules. I really appreciate. I have a question about your drawing at 7:30. Do we have to follow another rule as "one coming in, one coming out at each vertex"? Then, to follow the rule, should we rearrange the positron arrow downward and the photon is vertically upward, indicating that the photon is the product after the interaction?
