  • @rdcruick watch the previous videos of projectile motion added by sal sir in the playlist physics it willl explain well

  • He finds changing colors to be harder than physics problems -_-

  • very good tutorial...you are doing a very good work!!

  • hi can someone explain why the magnitude of the final velocity is equal to the initial velocity?

  • TI-85!

  • How do i find the distance and initial velocity if only the angle and height is given?

  • @khanacademy

    hi sal ,

    so i have a question about the vertical velocity , correct me if i was wrong so to get the normal average velocity we do it like this ''delta''V =(Vi+Vf)/2 , but here when you calculated the vertical velocity which is also ''delta''V you calculated it like this ''delta''V = (Vf-Vi) and you used the same formula for the average velocity which is: a=''delta''V/''delta''t so whtat's the difference between those two velocities ?
