  where did they get the -120?

•

  If you referring to the table, it should be -80 units of momentum in the System Total row. The answer is still leftward.

  When an object is placed in focus, and the one incident ray strikes the principal pole it will reflect back with the same angle as the angle of incidence and the second incident ray is parallel to the principal axis and it will reflect back through the focus.. Then there are the chances for reflecting rays to intersect each other. Please need your valuable answer

  Note: Momentum is only conserved in elastic collisions, no external forces at work. In real life there are generally some external forces at work ie. friction. Its close but not zero. Also an obect at rest has zero momentum only in that frame of reference. Ie. the car parked in the street MxV= Mx0=0. But the earth is moving and so is the car. So in a different frame of reference the stationary car can have momentum.

  I love your video it's straight to the point but I don't understand something In 2:34 you introduced an axis y and x, which I get. I also know that sinα is for y and cosα is for x. When solving for y related forces we normally do Wsinα to get Fnorm but here and in the Mechanics textbook they do Fnorm=Wcosα, and Fii=Wsinα why?

• 
  @PhysicsclassroomVideosАй бұрын

  Nope. I've done it identical to your book. Eqns are at 3:40. Sine is for parallel or x and cosine is for perpendicular or y and generally = to Fnorm. Explanation as to why is given seconds earlier.

• 
  @ifiokekott3833Ай бұрын

  @@PhysicsclassroomVideos yes that's my question In physics sin is used for the y axis and cos for x axis but here is flipped why, even in textbooks?

• 
  @PhysicsclassroomVideosАй бұрын

  Because the angle Theta is between the weight vector and the y axis. For most other situations the angle Theta is between the vector to be resolved and the x axis.

  Thanks! These videos are very useful as a complement to a book on the electromagnetic field I am reading, but all of this is way more complex than It seems. So, I have a doubt concerning the can. It is supposed to be neutral, yet it looks like it has a small field (electric? electrostatic? electromagnetic?) around it because it did attract a couple of paper shreds. From another video I learned that neutrally charged objects are always attracted by charged ones, as is the case with the PVC tube. So the can cannot be neutral, because in that case it would have been attracted by the tube, not repelled (as the other video explains, if two objects repell each other, they are both charged). So what am I missing?

• 
  @PhysicsclassroomVideosАй бұрын

  The can is neutral. It is never repelled by another object. Within the can are charged particles - electrons and protons. The protons are fixed in place. The electrons can move. Electrons would move toward an external + object and away from an external negative object. This is what polarizes the can, making it attired to both + and - objects

• 
  @scientechlsp7793Ай бұрын

  @@PhysicsclassroomVideos OK! I think I got it. I watched again the last part of the video about polarization and I can see that there's no charging involved here, but "polarization". So, what happens is that the neutral object's electrons move to one end of the object when another polarized object comes near, right? As if they became magnets in the presence of a polarized object?
