Uniform Circular Motion Angular Velocity Rotation Around A Fixed Axis 10.7 newton’s second law for rotation. newton’s second law for rotation, ∑iτi = iα, says that the sum of the torques on a rotating system about a fixed axis equals the product of the moment of inertia and the angular acceleration. this is the rotational analog to newton’s second law of linear motion. V. t. e. rotation around a fixed axis or axial rotation is a special case of rotational motion around an axis of rotation fixed, stationary, or static in three dimensional space. this type of motion excludes the possibility of the instantaneous axis of rotation changing its orientation and cannot describe such phenomena as wobbling or precession.
Physics Uniform Circular Motion 7 2 Angular Speed And Velocity ω = Δθ Δt, (6.1.6) where an angular rotation Δθ takes place in a time Δt. the greater the rotation angle in a given amount of time, the greater the angular velocity. the units for angular velocity are radians per second (rad s).angular velocity ω is analogous to linear velocity v. A system undergoing uniform circular motion has a constant angular velocity, but points at a distance r from the rotation axis have a linear centripetal acceleration. a system undergoing nonuniform circular motion has an angular acceleration and therefore has both a linear centripetal and linear tangential acceleration at a point a distance r. Figure 6.7 shows an object moving in a circular path at constant speed. the direction of the instantaneous tangential velocity is shown at two points along the path. acceleration is in the direction of the change in velocity; in this case it points roughly toward the center of r. We define angular velocity ω as the rate of change of an angle. in symbols, this is ω = Δθ Δt ω = Δ θ Δ t, where an angular rotation Δ θ takes place in a time Δ t. the greater the rotation angle in a given amount of time, the greater the angular velocity. the units for angular velocity are radians per second (rad s).

The angular displacement of the particles of a rotating object is irrespective of the radius. a particle that is \(10\text{ m}\) out from the axis of rotation will have the same angular velocity as an object that is \(100\text{ m}\) from the axis of rotation. this is easily observed by looking out at the stars at night. Uniform circular motion is a specific type of motion in which an object travels in a circle with a constant speed. for example, any point on a propeller spinning at a constant rate is executing uniform circular motion. other examples are the second, minute, and hour hands of a watch. it is remarkable that points on these rotating objects are.
