    en.wikipedia.org/wiki/Rindler_coordinates

    Rindler chart, for = in equation , plotted on a Minkowski diagram. The dashed lines are the Rindler horizons The dashed lines are the Rindler horizons The worldline of a body in hyperbolic motion having constant proper acceleration α {\displaystyle \alpha } in the X {\displaystyle X} -direction as a function of proper time τ {\displaystyle ...

  3. Non-inertial reference frame - Wikipedia

    en.wikipedia.org/wiki/Non-inertial_reference_frame

    A non-inertial reference frame (also known as an accelerated reference frame [1]) is a frame of reference that undergoes acceleration with respect to an inertial frame. [2] An accelerometer at rest in a non-inertial frame will, in general, detect a non-zero acceleration. While the laws of motion are the same in all inertial frames, in non ...

  4. Inertial frame of reference - Wikipedia

    en.wikipedia.org/wiki/Inertial_frame_of_reference

    All frames of reference with zero acceleration are in a state of constant rectilinear motion (straight-line motion) with respect to one another. In such a frame, an object with zero net force acting on it, is perceived to move with a constant velocity, or, equivalently, Newton's first law of motion holds. Such frames are known as inertial.

  5. Piston motion equations - Wikipedia

    en.wikipedia.org/wiki/Piston_motion_equations

    For rod length 6" and crank radius 2" (as shown in the example graph below), numerically solving the acceleration zero-crossings finds the velocity maxima/minima to be at crank angles of ±73.17615°. Then, using the triangle law of sines, it is found that the rod-vertical angle is 18.60647° and the crank-rod angle is 88.21738°. Clearly, in ...

  6. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    The linear motion can be of two types: uniform linear motion, with constant velocity (zero acceleration); and non-uniform linear motion, with variable velocity (non-zero acceleration). The motion of a particle (a point-like object) along a line can be described by its position x {\displaystyle x} , which varies with t {\displaystyle t} (time).

  7. Accelerometer - Wikipedia

    en.wikipedia.org/wiki/Accelerometer

    An accelerometer measures proper acceleration, which is the acceleration it experiences relative to freefall and is the acceleration felt by people and objects. [2] Put another way, at any point in spacetime the equivalence principle guarantees the existence of a local inertial frame, and an accelerometer measures the acceleration relative to that frame. [4]

  8. Jerk (physics) - Wikipedia

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

    Deceleration ramp down — positive jerk limit; linear increase in acceleration to zero; quadratic decrease in velocity; approaching the desired position at zero speed and zero acceleration Segment four's time period (constant velocity) varies with distance between the two positions.

  9. Proper acceleration - Wikipedia

    en.wikipedia.org/wiki/Proper_acceleration

    In relativity theory, proper acceleration [1] is the physical acceleration (i.e., measurable acceleration as by an accelerometer) experienced by an object. It is thus acceleration relative to a free-fall , or inertial , observer who is momentarily at rest relative to the object being measured.
