If I understand correctly do you mean to say like you roll a ball across a perfectly smooth surface and the air or water resistance or friction is known. Therefore because the ball decelerates once it is rolled then the initial velocity can be calculated? Like at t = 0 velocity was 1 m/s but...
I have read that to increase motor magnetism that an increase in the windings increases the number of tiny magnets that can be used to provide the magnetic force. I have also read that increasing the cross section of the rotor increases the efficiency. Finally I have read that increasing the...
