    Resumen

    El estudio revela que la diferencia entre el tiempo de efemérides y el tiempo universal (DeltaT) y las variaciones de la longitud del día (Delta LOD) están estrechamente relacionadas con los ciclos solares. Estas variaciones han disminuido con el tiempo, con Delta (LOD) ahora aproximadamente en fase con el número de manchas solares.

    Uniform Circular Motion01:14

    Uniform Circular Motion

    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 undergoing uniform circular motion. The second, minute, and hour hands of a watch also undergo uniform circular motion. It is hard to believe that points on these rotating objects are actually accelerating, even though the rotation rate is constant. To understand this, we must analyze the motion in terms of...

    Gyroscope: Precession01:24

    Gyroscope: Precession

    Precession can be demonstrated effectively through a spinning top. If a spinning top is placed on a flat surface near the surface of the Earth at a vertical angle and is not spinning, it will fall over due to the force of gravity producing a torque acting on its center of mass. However, if the top is spinning on its axis, it precesses about the vertical direction, rather than topple over due to this torque. Precessional motion is a combination of a steady circular motion of the axis and the...

    Apparent Weight and the Earth's Rotation01:28

    Apparent Weight and the Earth's Rotation

    Since all objects on the Earth's surface move through a circle every 24 hours, there must be a net centripetal force on each object, directed towards the center of that circle. The points of the north and south poles are the only exception to this rule.
    For an object on the Earth's equator, the net centripetal force that accounts for its rotation is the Earth's pull towards its center, or the weight minus the normal force that prevents it from piercing into the Earth's surface....

    Circular Orbits and Critical Velocity for Satellites01:16

    Circular Orbits and Critical Velocity for Satellites

    The Moon orbits around the Earth. In turn, the Earth (and other planets) orbit the Sun. The space directly above our atmosphere is filled with artificial satellites in orbit. One can examine the circular orbit, the simplest kind of orbit, to understand the relationship between the speed and the period of planets and satellites with respect to their positions and the bodies that they orbit.
    Nicolaus Copernicus (1473-1543) first suggested that the Earth and all other planets orbit the Sun in...

    Energy of a Satellite in a Circular Orbit01:11

    Energy of a Satellite in a Circular Orbit

    Thousands of artificial satellites orbit the Earth every day at various distances from the Earth. Satellites that orbit the Earth below an altitude of 1,600 km are considered to be orbiting in low-Earth orbit (LEO). Research satellites and Earth observation satellites are usually placed in LEO, and mostly orbit the Earth in elliptical orbits. Navigation satellites are placed in medium-Earth orbit (MEO), ranging from 2,000 km to 36,000 km from the surface of the Earth. Meanwhile, communication...

    Simple Harmonic Motion and Uniform Circular Motion01:42

    Simple Harmonic Motion and Uniform Circular Motion

    While simple harmonic motion and uniform circular motion may be two separate concepts, they correlate and interlink with each other. Simple harmonic motion is an oscillatory motion in a system where the net force can be described by Hooke's law, while uniform circular motion is the motion of an object in a circular path at constant speed.
    There is an easy way to produce simple harmonic motion by using uniform circular motion. For instance, consider a ball attached to a uniformly rotating...
