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

Very good video. Thinking about a tracked tractor made me intuitively realise how the instantaneous velocity with respect to the ground is zero.

Provided the foot does not slip. Does this apply to the foot contact phase during human running? Our assumption is yes. Can you confirm?

[_bit]

is he... writing mirrored? that's impressive

[sarthakkansal]

The velocity of rolling without slipping contains Vcm and Vcm.how can they both be equal in rolling without slipping?

In india we study this in class 11th😂😂😂
