... d. the angular displacement remains constant. e. the rotational kinetic energy never changes. ANS: b 69. A sphere with a 3 kg m 2 moment of inertia about an axis through its center has its angular velocity changed by 4 rad/s owing to a 2 N m torque applied about that axis for 6 s. If its initial ...

... Look at the balls being juggled in Figure 11–5. If you consider the system to be only one ball, then it has several external forces exerted on it. The force of the juggler’s hand does work, giving the ball its original kinetic energy. After the ball leaves his hand, only the force of gravity acts on ...

... 1. You find your mass to be 42 kg on a weighing machine. Is your mass more or less than 42 kg? Ans.: When you weigh your body, an upward force acts on it. This upward force is the buoyant force. As a result, the body gets pushed slightly upwards, causing the weighing machine to show a reading less t ...
