Rotational motion formulas. Rotational Kinematics Linear Angular Rotational Inertia and Energy point objects Rotational inertia Rotational inertia solid objects Parallel axis theorem Rotational kinetic energy Torque and Angular Momentum Rotational Motion Torque Newtons 2nd law. It can be defined as distance taken in a given time. Where ω is the angular velovity r is the radius and v is the tangential velocity.
If a body executes rotational motion the equations of motions are written as ω ω 0 αt θ ω 0 t ½αt 2. Evaluate problem solving strategies for rotational kinematics. To determine this equation we recall a familiar kinematic equation for translational or straight-line motion.
A similar formulas v. ω 2πT2πf where T is the period of the motion and f is the frequency. Rotational Motion Rigid Body-A rigid body consists of a number of particles confined to a fixed geometrical shape and size in such a way that the distance between any pair of particles always remains constant.
Rotational Inertia Understand the relationship between force mass. Linear speed and tangential speed gives the same meaning for circular motion. One prime focus of physics is the study of motion.
Derive rotational kinematic equations. For rotational motion we will find direct analogs to force and mass that behave just as we would expect from our earlier experiences. 2πr which is the circumference of the circle object.
Rotational Motion We are going to consider the motion of a rigid body about a fixed axis of rotation. Rotational Inertia and Moment of Inertia Before we can consider the rotation of anything other than a point mass like the one in Figure 2 we must extend the idea of rotational inertia to all types of objects. 103Dynamics of Rotational Motion.
