Angular Velocity - an overview ScienceDirect Topics

Webangular velocity: A vector quantity describing an object in circular motion; its magnitude is equal to the speed of the particle and the direction is perpendicular to the plane of its circular motion. A force that causes motion in a curved path is called a centripetal force. Uniform circular motion is an example of centripetal force in action. WebExample 3: Calculating the Torque in a Kick. The person whose leg is shown in Figure 2 kicks his leg by exerting a 2000-N force with his upper leg muscle. The effective perpendicular lever arm is 2.20 cm.
