4:00 Bobby says, "Work is the definite integral of force with respect to position." It might be worth including the dot product in there (or at least a mention that this is directionally dependent). Since you always speak the equation out, how do you say verbally that this equation only considers components of forces that are in the direction of motion in a succinct way? In the equation on the screen, you have it denoted as F_x dx, so maybe that's enough for this video, especially since it's not about work. (Although that version of the equation is already a slightly "special-case" equation.) But overall, it looks very good. I especially like the live updating slow-motion graphs. It's well timed and looks very professional.
Your comment about my not being crystal clear about the work equation gets to one of the difficulties of making these videos. Namely, deciding how much detail to put in them. If I put in every detail, then the videos are way too long. I try to find a happy medium. I decided here to not get into too much detail about the work equation. All I really wanted to get across is that students often confuse these two equations and, hopefully, my highlighting that will mitigate that some. I'll leave the detail about the work equation to my videos specifically about work. Thanks for the kudos about the graphs. I'm proud of those!
You have explained explained everything with refrences to the real life and evoluted the youtube and old study mode.But physical optics and fluid dynamics are still the topics which prevents most of the students to be engrossed in the real physics.
great video sir,one question popped up in my mind its out of topic here but please help..Does torque increase centripetal force?If it doesn't then when we apply torque, magnitude of velocity is increasing and if we subtract two velocity vectors,the difference is increasing and isn't acceleration increasing?
Torque does not directly increase centripetal force. Torque occurs because there is a force with a component that is either parallel with, or opposite the direction of the linear velocity of part of the rigid body. Centripetal force by contrast, is the net force that is radially inward, to sustain the circular motion so it is something other than a straight line motion. It takes a net torque, accumulated through time and rotational displacement, for the angular velocity to change. When it does, it will subsequently require more force to cause centripetal acceleration once rotating at a higher angular velocity, in order to sustain the motion in a circular path.
Integral def helps me a lot inside of what impulse J is .
Thanks a bunch! I’m learning physics c from you
Looks good!
Thanks!

@@FlippingPhysics Definitely makes sense. We have to simplify all the time. Just wanted to make sure it was a decision and not an accident!
Thanks! Always good to check.
A month old comment?

I'll get there. Have patience.
Our teacher (Shoutout to Mr. Caligiuri half hollow hills hsw btw lol!) taught us " jimpulse " to remember the J !
