    On the Transformation of Torques Between the Laboratory and Center

    On the transformation of torques between the laboratory and center of mass reference frames Rodolfo A. Diaz,∗ William J. Herrera† Universidad Nacional de Colombia, Departamento de F´ısica. Bogot´a, Colombia. Abstract It is commonly stated in Newtonian Mechanics that the torque with respect to the laboratory frame is equal to the torque with respect to the center of mass frame plus a R × F factor, with R being the position of the center of mass and F denoting the total external force. Although this assertion is true, there is a subtlety in the demonstration that is overlooked in the textbooks. In addition, it is necessary to clarify that if the reference frame attached to the center of mass rotates with respect to certain inertial frame, the assertion is not true any more. PACS {01.30.Pp, 01.55.+b, 45.20.Dd} Keywords: Torque, center of mass, transformation of torques, fictitious forces. In Newtonian Mechanics, we define the total external torque of a system of n particles (with respect to the laboratory frame that we shall assume as an inertial reference frame) as n Next = ri × Fi(e) , i=1 X where ri, Fi(e) denote the position and total external force for the i − th particle. The relation between the position coordinates between the laboratory (L) and center of mass (CM) reference frames 1 is given by ′ ri = ri + R , ′ with R denoting the position of the CM about the L, and ri denoting the position of the i−th particle with respect to the CM, in general the prime notation denotes variables measured with respect to the CM.

  • THE PROBLEM with SO-CALLED FICTITIOUS FORCES Abstract 1

    THE PROBLEM with SO-CALLED FICTITIOUS FORCES Abstract 1

    THE PROBLEM WITH SO-CALLED FICTITIOUS FORCES Härtel Hermann; University Kiel, Germany Abstract Based on examples from modern textbooks the question will be raised if the traditional approach to teach the basics of Newton´s mechanics is still adequate, especially when inertial forces like centrifugal forces are described as fictitious, applicable only in non-inertial frames of reference. In the light of some recent research, based on Mach´s principles and early work of Weber, it is argued that the so-called fictitious forces could be described as real interactive forces and therefore should play quite a different role in the frame of Newton´s mechanics. By means of some computer supported learning material it will be shown how a fruitful discussion of these ideas could be supported. 1. Introduction When treating classical mechanics the interaction forces are usually clearly separated from the so- called inertial forces. For interaction forces Newton´s basic laws are valid, while for inertial forces especially the 3rd Newtonian principle cannot be applied. There seems to be no interaction force which can be related to the force of inertia and therefore this force is called fictitious and is assigned to a fictitious world. The following citations from a widespread German textbook (Bergmann Schaefer 1998) may serve as a typical example, which is found in similar form in many other German as well as American textbooks. • Zu den in der Natur beobachtbaren Kräften gehören schließlich auch die sogenannten Scheinkräfte oder Trägheitskräfte, die nur in Bezugssystemen wirken, die gegenüber dem Fundamentalsystem der fernen Galaxien beschleunigt sind. Dazu gehören die Zentrifugalkraft und die Corioliskraft.

    Relativity with a Preferred Frame. Astrophysical and Cosmological Implications Monday, 21 August 2017 15:30 (30 Minutes)

    6th International Conference on New Frontiers in Physics (ICNFP2017) Contribution ID: 1095 Type: Talk Relativity with a preferred frame. Astrophysical and cosmological implications Monday, 21 August 2017 15:30 (30 minutes) The present analysis is motivated by the fact that, although the local Lorentz invariance is one of thecorner- stones of modern physics, cosmologically a preferred system of reference does exist. Modern cosmological models are based on the assumption that there exists a typical (privileged) Lorentz frame, in which the universe appear isotropic to “typical” freely falling observers. The discovery of the cosmic microwave background provided a stronger support to that assumption (it is tacitly assumed that the privileged frame, in which the universe appears isotropic, coincides with the CMB frame). The view, that there exists a preferred frame of reference, seems to unambiguously lead to the abolishmentof the basic principles of the special relativity theory: the principle of relativity and the principle of universality of the speed of light. Correspondingly, the modern versions of experimental tests of special relativity and the “test theories” of special relativity reject those principles and presume that a preferred inertial reference frame, identified with the CMB frame, is the only frame in which the two-way speed of light (the average speed from source to observer and back) is isotropic while it is anisotropic in relatively moving frames. In the present study, the existence of a preferred frame is incorporated into the framework of the special relativity, based on the relativity principle and universality of the (two-way) speed of light, at the expense of the freedom in assigning the one-way speeds of light that exists in special relativity.

  • The Sagnac Effect: Does It Contradict Relativity?

    The Sagnac Effect: Does It Contradict Relativity?

    The Sagnac Effect: Does it Contradict Relativity? By Doug Marett 2012 A number of authors have suggested that the Sagnac effect contradicts the original postulates of Special Relativity, since the postulate of the constancy of the speed of light is violated in rotating systems. [1,2,3] Sagnac himself designed the experiment of 1913 to prove the existence of the aether [4]. Other authors have attempted to explain the effect within the theoretical framework of relativity, even going as far as calling the effect “relativistic”.[5] However, we seek in this paper to show how the Sagnac effect contravenes in principle the concept of the relativity of time and motion. To understand how this happens and its wider implications, it is necessary to look first at the concept of absolute vs. relative motion, what the Sagnac effect implies about these motions, and what follows logically about the broader notions of space and time. Early Ideas Regarding Rotation and Absolute Motion: The fundamental distinction between translational and rotational motion was first pointed out by Sir Isaac Newton, and emphasized later by the work of Ernest Mach and Heinrich Hertz. One of the first experiments on the subject was Newton’s bucket experiment of 1689. It was an experiment to demonstrate that true rotational motion cannot be defined as relative rotation of a body with respect to surrounding bodies – that true motion and rest should be defined relative to absolute space instead. In Newton’s experiment, a bucket is filled with water and hung by a rope. If the rope is twisted around and around until it is tight and then released, the bucket begins to spin rapidly, not only with respect to the observers watching it, but also with respect to the water in the bucket, which at first doesn’t move and remains flat on its surface.
  • 14 Newton's Laws #1: Using Free Body Diagrams

    14 Newton's Laws #1: Using Free Body Diagrams

    Chapter 14 Newton’s Laws #1: Using Free Body Diagrams 14 Newton’s Laws #1: Using Free Body Diagrams If you throw a rock upward in the presence of another person, and you ask that other person what keeps the rock going upward, after it leaves your hand but before it reaches its greatest height, that person may incorrectly tell you that the force of the person’s hand keeps it going. This illustrates the common misconception that force is something that is given to the rock by the hand and that the rock “has” while it is in the air. It is not. A force is all about something that is being done to an object. We have defined a force to be an ongoing push or a pull. It is something that an object can be a victim to, it is never something that an object has. While the force is acting on the object, the motion of the object is consistent with the fact that the force is acting on the object. Once the force is no longer acting on the object, there is no such force, and the motion of the object is consistent with the fact that the force is absent. (As revealed in this chapter, the correct answer to the question about what keeps the rock going upward, is, “Nothing.” Continuing to go upward is what it does all by itself if it is already going upward. You don’t need anything to make it keep doing that. In fact, the only reason the rock does not continue to go upward forever is because there is a downward force on it.

    Sliding and rolling: the physics of a rolling ball J Hierrezuelo Secondary School I B Reyes Catdicos (Vdez- Mdaga),Spain and C Carnero University of Malaga, Spain We present an approach that provides a simple and there is an extra difficulty: most students think that it adequate procedure for introducing the concept of is not possible for a body to roll without slipping rolling friction. In addition, we discuss some unless there is a frictional force involved. In fact, aspects related to rolling motion that are the when we ask students, 'why do rolling bodies come to source of students' misconceptions. Several rest?, in most cases the answer is, 'because the didactic suggestions are given. frictional force acting on the body provides a negative acceleration decreasing the speed of the Rolling motion plays an important role in many body'. In order to gain a good understanding of familiar situations and in a number of technical rolling motion, which is bound to be useful in further applications, so this kind of motion is the subject of advanced courses. these aspects should be properly considerable attention in most introductory darified. mechanics courses in science and engineering. The outline of this article is as follows. Firstly, we However, we often find that students make errors describe the motion of a rigid sphere on a rigid when they try to interpret certain situations related horizontal plane. In this section, we compare two to this motion. situations: (1) rolling and slipping, and (2) rolling It must be recognized that a correct analysis of rolling without slipping.

I.e. in a reference system which is at rest or in constant motion. What happens when reference system is rotating? Then „inertial forces“ will appear. A mass at rest will experience a centrifugal force. A mass that is in motion will experience a Coriolis force. 3 Which reference system do we want to use? z y x 4 Stewart, 2007 Which reference system do we want to use? We like to use a Cartesian coordinate system at the ocean surface convention: x eastward y northward z upward This reference system rotates with the earth around its axis.
