help me write a response back to my classmaate likando 1. I small force can exert a greater torque force depending on its position in relation to the pivot, i.e. it being farther from the pivot. 2.If the net force of a system is zero, then the torque doesn't also have to be zero as this happens when equal but opposite forces are enacted oppositely on an object, canceling out the forces, causing the net force to be zero. If the net torque on a system is zero that does not mean the net force is zero as for angular momentum to be conserved the torque must remain at zero, for example of a driver with their arms and legs tucked while rotating to drive faster, if gravity is acting the net force isn't zero but the torque is because gravity is acting on the center of their mass. 3. The moment of inertia would be the smallest if it was passing perpendicular to the books largest surface, axis of rotation, because this is where the mass of the book would be distributed more compactly. 4.Within an isolated system only is momentum conserved, but when external forces like air resistance and friction is taken in consideration the rotating object slows down. 5. No, there will be no mass distribution along the axis which is what is needed for rotational motion to have for rotational inertia and torques to act on it
