  2. Tangential speed - Wikipedia

    en.wikipedia.org/wiki/Tangential_speed

    However, tangential speed, unlike rotational speed, depends on radial distance (the distance from the axis). For a platform rotating with a fixed rotational speed, the tangential speed in the centre is zero. Towards the edge of the platform the tangential speed increases proportional to the distance from the axis. [2] In equation form: , where ...

  3. Circular motion - Wikipedia

    en.wikipedia.org/wiki/Circular_motion

    Examples of circular motion include: special satellite orbits around the Earth (circular orbits), a ceiling fan's blades rotating around a hub, a stone that is tied to a rope and is being swung in circles, a car turning through a curve in a race track, an electron moving perpendicular to a uniform magnetic field, and a gear turning inside a ...

  4. Speed - Wikipedia

    en.wikipedia.org/wiki/Speed

    Angular speed and tangential speed on a disc Tangential speed is the speed of an object undergoing circular motion, i.e., moving along a circular path. [6] 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 ...

  5. Equations of motion - Wikipedia

    en.wikipedia.org/wiki/Equations_of_motion

    A differential equation of motion, usually identified as some physical law (for example, F = ma) and applying definitions of physical quantities, is used to set up an equation for the problem. [ clarification needed ] Solving the differential equation will lead to a general solution with arbitrary constants, the arbitrariness corresponding to a ...

  6. Centripetal force - Wikipedia

    en.wikipedia.org/wiki/Centripetal_force

    The speed in the formula is squared, so twice the speed needs four times the force, at a given radius. This force is also sometimes written in terms of the angular velocity ω of the object about the center of the circle, related to the tangential velocity by the formula v = ω r {\displaystyle v=\omega r} so that F c = m r ω 2 ...

  7. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    Tangential speed; Rotational frequency ... An example of linear motion is an athlete running a 100-meter dash along a straight track. [2] ... Defining equation

    “As an example, a serving of alcohol-- 12 ounces of light beer, 5 ounces of wine, or 1.5 ounces of liquor-- is generally between 100 to 150 calories.” Ahead, read on to learn tips for making ...

  9. Acceleration - Wikipedia

    en.wikipedia.org/wiki/Acceleration

    The tangential component is given by the angular acceleration , i.e., the rate of change = ˙ of the angular speed times the radius . That is, a t = r α . {\displaystyle a_{t}=r\alpha .} The sign of the tangential component of the acceleration is determined by the sign of the angular acceleration ( α {\displaystyle \alpha } ), and the tangent ...
