Question
T F The mass moments and products of inertia are always positive or zero. T F The friction force beneath a rolling (without slip) wheel does work only f the fixed surface of contact is curved. T F In polar coordinates, a particle moving with constant dr/dt and dtheta/dt will always have zero acceleration. T F The velocity and acceleration of a point P depend on the choice of reference frame? T F The work done by the friction force upon a block sliding on a rough plane depends on the path taken by the block.Explanation / Answer
