Friction and Cars

[manuboker]

Excellent good vibes physics lectures!! Making it easy to comprehend.

Your ability to write stuff inverted by the x axis is astounding.

Excuse me, I didn't quite understand one thing. You prove that static friction does no work by looking at car moving in a circle. But this is quite special example, what if we look at the straight path? Can we prove that static friction all the same does no work? Because dot product in that case won't be zero.

Sir, your videos are very helpful so please keep going....

How come we always feel this tiny "push" just before the car comes to rest when breaking?

[yugzed]

How is friction perpendicular to the motion of the object? Isnt it supposed to be always opposite to it?

[moviequotes]

sir, does the force applied by the driver on the brake pedal equals to the force applied by the pads to the rotor?
