  1. hey! um a student from india..nd i find your videos reallyyy helpful!! its like they are super reliable ! i can count on your videos even 1 day before my final exams ! thankyou so much ๐Ÿ™‚ ๐Ÿ˜€

  2. Pretty good one, as always ( of course ).
    Short request:ย  A parachute ย would be a great example, in it's different stages…
    ย Maybe next time.
    Have a great day, Mr. ย Anderson !

  3. For the last example (motionless car with a rope), would there be a static friction force vector opposite of the tension force vector?

  4. why is the force of friction on the car on the slope on the right? why isnt it to the back of the car since friction helps impede movement?

  5. Why is there no applied force or acceleration force in the second last example? Please answer asap I have a test on Monday..

  6. revisiting statics trying to get well grounded. once I get to that point the math will be just plugging in. I've noticed unless I know a subject thoroughly I get side tracked. looking forward to viewing your videos.

  7. i have a doubt mr anderson
    does weight depend on inclination?
    weight is the force with which an object attracted towards the center of earth.
    weight of an object w=mass*gravity
    the only possible way to increase or decrease the weight is either change in mass or change in gravity. in the video showed weight of an object on inclined surface is less when compared to weight of an object on horizantal surface.can u explain me how weight of an object depends on inclination?

  8. i've been watching alot of videos about free body diagrams and woa my teacher is actually explaining everything wrong that's why i couldn't understand her. i wish i had a better teacher because im always having a hard time in science.

  9. When you're shooting the car into the air, there should be air friction, right? I'm not sure; this is my first time learning this.

  10. ๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘………….. great

  11. I have always been told that the normal force acts from the where the object and the ground meet (contrary to your depiction with the normal force acting from the object centre), but that would that would make it difficult to decompose into x and y axes. It makes more sense to me that way however, as the normal force is a force acting from the ground on the object. Is one more corect than the other?

  12. My teacher spent 1 semester teaching these things and you know what i understood 0% about free body diagram. This video taught me and gave the most crystal clear idea about free body diagrams. Thank you

  13. At 5:12 , since the car is in rest at the peak of its flight, don't we need an upward force to balance the car if only for that instance. If we take the frame where that car is in rest, don't we have to think about the upward force too?

  14. when the car is inclined at an angle as it accelerates downward, why is it that there was no label for acceleration which is the opposite of friction?

  15. superbly explained.Thank you very much. i felt if before the diagram is drawn ,it is made clear if we are to take account of Air . It will help.

  16. I thought that this video was too short. I wish the explanations had been a little more thorough and terms defined. And, I am a great fan.

  17. very helpful! how do you know how long you should make the vector arrows? for example the tension arrow you drew for the last example was slightly longer than the one for the for the friction arrow where the car was rolling down the angled platform.
