A big take-away from this explanation is that the top of a car's tire rolling without slipping is actually going down the roadway at twice whatever speed the car is traveling. This also gives you a 2:1 lever should you ever need to push a car and find it difficult. Simply push from the top of a tire and your required force will become essentially 1/2 of what's needed by pushing from behind.
Animation at the end helped a bucket. I was trying to figure out intuitively why the point at 3:10 had non-zero x velocity

Nice animation in the end.
Very good video. Thinking about a tracked tractor made me intuitively realise how the instantaneous velocity with respect to the ground is zero.
its so fucking clear now, thank you
I loved the video professor...
The velocity of rolling without slipping contains Vcm and Vcm.how can they both be equal in rolling without slipping?
Magnitude of vector |V̅cm|= Vcm
Provided the foot does not slip. Does this apply to the foot contact phase during human running? Our assumption is yes. Can you confirm?
is he... writing mirrored? that's impressive
Either that’s a pun or u dont know😂
mirroring the video clip, not the presenter
@@hstevefrancis1003 Yes ... you are correct. Look at his shirt, the buttons are on the wrong side for a man's shirt.
How is this board work?
lightboard.info explains how.
thank you very much !
alicopter?
In india we study this in class 11th😂😂😂
