  2. Displacement (geometry) - Wikipedia

    en.wikipedia.org/wiki/Displacement_(geometry)

    In considering motions of objects over time, the instantaneous velocity of the object is the rate of change of the displacement as a function of time. The instantaneous speed, then, is distinct from velocity, or the time rate of change of the distance travelled along a specific path. The velocity may be equivalently defined as the time rate of ...

  3. Distance - Wikipedia

    en.wikipedia.org/wiki/Distance

    The distance travelled by an object is the length of a specific path travelled between two points, [6] such as the distance walked while navigating a maze. This can even be a closed distance along a closed curve which starts and ends at the same point, such as a ball thrown straight up, or the Earth when it completes one orbit .

  4. Equations for a falling body - Wikipedia

    en.wikipedia.org/wiki/Equations_for_a_falling_body

    Instantaneous velocity of a falling object that has travelled distance on a planet with mass , with the combined radius of the planet and altitude of the falling object being , this equation is used for larger radii where is smaller than standard at the surface of Earth, but assumes a small distance of fall, so the change in is small and ...

  5. Absement - Wikipedia

    en.wikipedia.org/wiki/Absement

    Just as displacement and its derivatives form kinematics, so do displacement and its integrals form "integral kinematics". [9] Fluid flow in a throttle: A vehicle's distance travelled results from its throttle's absement. The further the throttle has been opened, and the longer it's been open, the more the vehicle's travelled.

  6. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    For convenience, consider contact with the spring occurs at t = 0, then the integral of the product of the distance x and the x-velocity, xv x dt, over time t is ⁠ 1 / 2 ⁠ x 2. The work is the product of the distance times the spring force, which is also dependent on distance; hence the x 2 result.

  7. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    Since linear motion is a motion in a single dimension, the distance traveled by an object in particular direction is the same as displacement. [4] The SI unit of displacement is the metre . [ 5 ] [ 6 ] If x 1 {\displaystyle x_{1}} is the initial position of an object and x 2 {\displaystyle x_{2}} is the final position, then mathematically the ...

  8. Kinematics - Wikipedia

    en.wikipedia.org/wiki/Kinematics

    The distance travelled is always greater than or equal to the displacement. ... A displacement consists of the combination of a rotation and a translation.

  9. Motion - Wikipedia

    en.wikipedia.org/wiki/Motion

    Motion is mathematically described in terms of displacement, distance, velocity, acceleration, ... blood has been found to travel at approximately 0.33 m/s.
