Which quantity plays the role of mass in Newton's second law for rotation? A point mass of 2.0 kg is 0.50 m from an axis. Its rotational inertia is The same mass is moved to three times the distance from the axis. Its rotational inertia A 10 N force acts perpendicular to a 0.30 m wrench. The torque is A net torque of 8.0 N m acts on an object with I = 2.0 kg m². The angular acceleration is A solid disk and a hoop have equal mass and radius. Which statement is correct? A rod is spun first about its centre, then about one end. The rotational inertia about the end is A string is wound on a pulley and does not slip. A hanging mass falls with acceleration a. The pulley's angular acceleration is Why is the tension in the string of a pulley system less than mg for an accelerating hanging mass? Which change would give a wheel the greater angular acceleration under the same torque? Rotational inertia of point masses? — I = Σmr², in kg m² Newton's second law for rotation? — τ_net = Iα Torque formula? — τ = rF sinθ Unit of torque? — N m Rotational inertia of a solid disk? — I = ½MR² Rotational inertia of a hoop? — I = MR² Rod about centre versus end? — (1/12)ML² versus (1/3)ML² Link between a and α for a string? — a = Rα, if the string does not slip Effect of doubling r on I? — I becomes four times larger Effect of larger I at the same torque? — Smaller angular acceleration Keep going with Lina
