<p>Well,I my in chapter 12: Rolling Torque Angular Momentum right now
My Question:
On an incline plane, frictionless = slipping
friction = without slipping? ?
when an object roll down a frictionless plane,which kind of energy is there: translational kinetic energy or rotational kinetic energy ??-----should it be translational though?? </p>
<p>For a question like the following :
Dish A and B are identical and roll across a floor with equal speeds. Then disk A rolls up an incline, reaching a max height H, and disk B moves up an incline that is identical execpt that it is frictionless. Is the max height reached by B less than, greater than, equal to H?</p>
<p>Right answer:
less ( rotational energy transfer to potential energy---explanation from the book)</p>
