This is a smartass video. I wish I have had him as my teacher. Your way of teaching is phenomenal! Ooh man I like all of your videos. Thanks a lot to the great professor and to @vkiledj for making it available.
@adamsx01x Wrong. ALL units are arbitrary. The advantage if SI is that all of the units were defined in powers of ten, making unit conversions simpler. A gram is the weight of a 1 cm^3 volume of 4 degree (C) water. That could easily have been mercury or any other arbitrary substance.
Consider how we measure time. There are ~365.25 days/yr, 24 hours/day, and so on. We could come up with a powers-of-ten unit for it, but we'd sometimes have to convert it back to 'days' for it to make sense.
Two objects A and B, are connected by a rigid rod that has a length L. The objects slide along perpendicular guide rails (i.e. A slides along the X-axis and B slides along the Y-axis). If A slides to the left with a constant speed "v," find the speed of B when the angle between the rod and X-axis is 60º.
This is a wicked good lecture. Thanks a lot

@stillmakesmelaugh no kg * m/ s ^ 2 is a newton

@stillmakesmelaugh i think kgm/s is a N (dot) S (dot meaning dot product)

can someone plz explain to me what Dm/Dt is ?
WaterLikey 1 year ago
@WaterLikey
dV is the change of velocity
dt is the change of time
dv/dt is the format of acceleration

lol kg x m/s is known as N or Newtons. This teacher fails.
FreakOfH311 2 years ago
This teacher is correct about the metric units for momentum. Remember, Force = (mass) (acceleration), therefore kg times m/s^2 gives you Newtons.
DartmouthAlum96 2 years ago
@FreakOfH311 No, the teacher is right, for a Newton is mass by acceleration (1N=1kg x 1m/s^2), not mass by speed (1kg x 1m/s).

Your answer should be in term of "v"

thank you for this, im taking physics now and this really helped me in my own professor's lecture on momentum & impulse.
