1. Does the shape/geometry of a rigid object affect the way it rotates (reaching a higher or lower rotation) under the effect of a torque? Discuss it. 2. Does the mass of a rigid object affect the way it rotates under the effect of a torque? Discuss it. The 2nd Newton Law for translation says that an acceleration on a mass is proportional to the force applied (a = F/m). For rotation, the same law relates the angular acceleration to the torque applied. What is the equivalent of mass, for rotation
