    Red and White Modern Group Project Presentation

    Michael Esmalla
    This document summarizes the key ideas of Einstein's theory of relativity. It begins by describing Newtonian mechanics and how it was successful but unable to fully explain experimental results. It then outlines Einstein's two postulates: 1) the laws of physics are the same in reference frames moving uniformly relative to each other, and 2) the speed of light in vacuum is constant. The consequences of special relativity include time dilation, where clocks in fast moving reference frames run slow compared to stationary clocks. The document concludes by thanking science teachers who have helped with the goals of making soap through chemical reactions.

    Theory of

    Relativity
    Michael P. Esmalla
    Instructor
    Newtonian (Classical)
    Relativity
    Newtonian mechanics and early ideas on space
    and time were formulated to describe the motion of such
    objects, and this
    formalism is very successful in describing a wide range
    of phenomena.
    According to Newtonian mechanics, if
    the potential difference (as well as the corresponding energy) is
    increased
    by a factor of 4, then the speed of the electron should be doubled to
    1.98c.

    However, experiments show that the speed of the electron — as


    well as the
    speeds of all other particles in the universe — always remains
    less than the
    speed of light, regardless of the size of the accelerating voltage.
    For example, if you perform an experiment while at rest in a
    laboratory, and an observer in a passing truck moving with
    constant velocity performs the same experiment, Newton’s laws
    may be applied to both sets of observations. Specifically, in the
    laboratory or in the truck a ball thrown up rises and returns to the
    thrower’s hand. Moreover, both events are measured to take the
    same time in the truck or in the laboratory, and Newton’s second
    law may be used in both frames to compute this time.
    Does this concept
    apply to velocity
    and force?
    Remember that velocity is the change of displacement over the change of
    time and force is the change of momentum over the change of time.
    Einstein’s Postulates
    1 Postulate
    st

    The laws of physics are the same in all reference systems that
    move uniformly with respect to one another. That is, basic
    laws have the same mathematical form for all observers
    moving at constant velocity with respect to one another.
    Einstein’s Postulates
    2 Postulate
    nd

    The Constancy of the Speed of Light: The speed of light in


    vacuum has the same value, c = 3.00x10 m/s, in all inertial
    8

    frames, regardless of the velocity of the observer or the


    velocity of the source emitting the light.
    Consequences of
    Special Relativity
    Time Dilation
    Clocks in S’ run slow with respect to stationary
    clocks in S.
    THANK
    YOU
    PROJECT
    GOALS
    MAKING
    SOAP
    Soap is a product of a chemical reaction that is very useful for
    everyday life. We provide a workshop program for making various
    types of soap with safe and easy chemicals for school
    extracurricular programs and general training.
    SPECIAL THANKS
