  2. Circular motion - Wikipedia

    en.wikipedia.org/wiki/Circular_motion

    Solving applications dealing with non-uniform circular motion involves force analysis. With a uniform circular motion, the only force acting upon an object traveling in a circle is the centripetal force. In a non-uniform circular motion, there are additional forces acting on the object due to a non-zero tangential acceleration.

  3. Tangential speed - Wikipedia

    en.wikipedia.org/wiki/Tangential_speed

    Tangential speed is the speed of an object undergoing circular motion, i.e., moving along a circular path. [1] A point on the outside edge of a merry-go-round or turntable travels a greater distance in one complete rotation than a point nearer the center. Travelling a greater distance in the same time means a greater speed, and so linear speed ...

  4. Rotation - Wikipedia

    en.wikipedia.org/wiki/Rotation

    Rotation or rotational motion is the circular movement of an object around a central line, known as an axis of rotation. A plane figure can rotate in either a clockwise or counterclockwise sense around a perpendicular axis intersecting anywhere inside or outside the figure at a center of rotation .

  5. Sun and planet gear - Wikipedia

    en.wikipedia.org/wiki/Sun_and_planet_gear

    The sun and planet gear converted the vertical motion of a beam, driven by a steam engine, into circular motion using a 'planet', a cogwheel fixed at the end of the connecting rod (connected to the beam) of the engine. With the motion of the beam, this revolved around, and turned, the 'sun', a second rotating cog fixed to the drive shaft, thus ...

  6. Rotating reference frame - Wikipedia

    en.wikipedia.org/wiki/Rotating_reference_frame

    In classical mechanics, the Euler acceleration (named for Leonhard Euler), also known as azimuthal acceleration [8] or transverse acceleration [9] is an acceleration that appears when a non-uniformly rotating reference frame is used for analysis of motion and there is variation in the angular velocity of the reference frame's axis. This article ...

  7. Classical central-force problem - Wikipedia

    en.wikipedia.org/wiki/Classical_central-force...

    In classical mechanics, the central-force problem is to determine the motion of a particle in a single central potential field.A central force is a force (possibly negative) that points from the particle directly towards a fixed point in space, the center, and whose magnitude only depends on the distance of the object to the center.

  8. Newton's theorem of revolving orbits - Wikipedia

    en.wikipedia.org/wiki/Newton's_theorem_of...

    The term "radial motion" signifies the motion towards or away from the center of force, whereas the angular motion is perpendicular to the radial motion. Isaac Newton derived this theorem in Propositions 43–45 of Book I of his Philosophiæ Naturalis Principia Mathematica , first published in 1687.

  9. Instant centre of rotation - Wikipedia

    en.wikipedia.org/wiki/Instant_centre_of_rotation

    Point A, at distance P 1-A from P 1, moves in a circular motion in a direction perpendicular to the link P 1-A, as indicated by vector V A. The same applies to link P 2-B: point P 2 is the instant center of rotation for this link and point B moves in the direction as indicated by vector V B.
