Webb8 feb. 2024 · Rotational Dynamics Rigid body A rigid body is defined as a solid body in which the particles are compactlt arranged so that the inter-particle distance is small and fixed and is not disturbed by any external forces applied. Such a body thus does not bend, stretch or vibrate when in motion. WebbWhen an object is acting upon by a force, it may move but it may also rotate. Torque is a measure of how much a force acting on an object causes that object to rotate. Suppose an object rotates about an axis, which we will call the pivot point ‘O’. We will call the force ‘F’.
WebbAngular Momentum Consider the net torque on a system of particles – is referred to as “angular momentum”( ) of ith particle – Internal, central forces exert zero net torque – Net torque must be provided by external forces: – If zero net external torque → angular momentum is conserved Both and depend on choice of origin – Unlike force and … WebbJust as force played a huge role in linear dynamics, we have a torque in rotational dynamics. We begin by defining this quantity and showing how it acts on objects in …

WebbIntroduction and Summary. Having developed the kinematics of rotational motion, we now turn to the dynamics of rotational motion. Unlike the linear case, however, we do not have Newton's Laws to guide us in our study. Instead, we try to develop parallel concepts to those of linear dynamics. Still, the study of rotational dynamics contains ...
