Practice AP Physics C: Mechanics Rotational Motion and Angular Momentum in the app →A nonzero net torque is described as causing changes in an object's:Besides changing rotational motion, a nonzero net torque results in changes of an object's:The rotational inertia of an object depends upon the distribution of:Units of radians are described as being:Radians are described as appearing in any relationship between angular quantities and:A quantity that changes when angular velocity changes over time is the angular:The change in angular momentum is given by the product of the average torque and the:Changes in the radius of a system result in changes in the system's:Changed rotational inertia leads to changes in angular velocity for a given:An ice skater spins faster and faster simply by doing what?Conservation of angular momentum is used to explain why which body keeps spinning?The magnitude of a skater's angular acceleration is described as proportional to her spin rate and her:A skater's moment of inertia is measured about which axis?A skater pulling her arms in reduces her rotational inertia, so her angular velocity must:Doubling the time a given average torque acts changes the change in angular momentum to:Two wheels of equal mass differ in rotational inertia because they differ in:Radians can be dropped from a final answer because their units are:Earth keeps spinning because, absent a net external torque, what is conserved?
