Yes, you do this in high school physics courses and in engineering courses in uni. Free body diagrams are the standard for calculating forces in static equilibrium and objects in motion by both engineers and physicists so of course you will see it in entry physics course and entry engineering courses, all the way to more integrated courses like when you start looking at systems as a whole.

[@kabouch]

4:18 I usually feel distracted when you use the negative sign before a 270-degree-vector in finding the sum of vectors. In my humble opinion, sum takes + sign. In other words, try to replace T with W in Fnet=T^2+W^2-2TWcos180, you'll end up with Fnet= 4W^2, but if you uswd T=-W you will end up with Fnet=0N

[@nabiyevali]

at the end you forgot about Fg, it suppose to be T= fk + Fg

[@e.b5911]

I think the same. But when adding the Fg, how will the forces along the X-axis be balanced since there is a constant velocity?

[@david3emmanuel]

I'm a bit confused about problem D at 29:38. Here the component of weight parallel to the incline (Fg) was not taken into account; was that intentional? Great video by the way :)

[@justplay2508]

Its because the velocity is constant

[@martincastillo5401]

That sine component of the weight should have been added to the kinetic friction to make the tension. 👌 Great video though.

[@wakuwaku3190]

In 3(d), why Fg disappeared as a force acting on the box?

[@CanucksFan4414]

Would the last example not have an x component of gravity acting against tension?

For the first example ("The Box"): the gravitational force and the normal force are *not* equal. W = -Fn

[@thedeathofbirth0763]

@30:17 There is a big mistake. I believe because you are running out of time. The Tension is calculated as following: (mgsin A+Fs=T).

[@zaidahmed6622]

you mean mgsin A + Fk = T because there is constant velocity therefore there is kinetic friction.

Hey, for 3(d) for the rope pulling up the block on the incline with friction, why is W not involved? Is it not Tension overcoming the forces of the friction and the weight pulling it down, with a net force of It going up? Thus tension = friction + mg sin tetha

[@zamhueljohntaberdo1253]

love you man

[@shivangsingh5834]

Sir in problem no. (e) , the acceleration is constant then the net force in the direction of X must be 0 , so why did you draw bigger magnitude of tension T , won't it be as equal as kinetic friction (FK)

[@ampa4989]

There is no net force if VELOCITY, not acceleration, is constant.

[@champagnepapi_ovo]

[@wrathofthewitchqueen]

20:00 aren't Fg and W the same thing? I'm lost

Love this video, but do not understand the very last part. Why is in the Fx direction is: T=fk; instead of 0=T-fk-WSin(theta)
