... 7. a. Friction, gravity, engine running. b. As described in 2, at constant speed, forces are balanced. c. Constant speed does not mean constant velocity, changing velocity means changing acceleration, so a force is created, which must be overcome by turning the wheel 8. a. According to Newton's thir ...

... A net torque would produce an angular acceleration. An object spinning at a constant rate will accelerate if the mass is redistributed farther or closer to the axis of rotation. Rotational Inertia is the resistance of a rotating object to changes in its rotational velocity-- it depends on mass, dist ...
