  2. Proper acceleration - Wikipedia

    en.wikipedia.org/wiki/Proper_acceleration

    The "acceleration of gravity" (involved in the "force of gravity") never contributes to proper acceleration in any circumstances, and thus the proper acceleration felt by observers standing on the ground is due to the mechanical force from the ground, not due to the "force" or "acceleration" of gravity. If the ground is removed and the observer ...

    en.wikipedia.org/wiki/Ultrarelativistic_limit

    Below are few ultrarelativistic approximations when .The rapidity is denoted : ⁡ Motion with constant proper acceleration: d ≈ e aτ /(2a), where d is the distance traveled, a = dφ/dτ is proper acceleration (with aτ ≫ 1), τ is proper time, and travel starts at rest and without changing direction of acceleration (see proper acceleration for more details).

  5. Acceleration - Wikipedia

    en.wikipedia.org/wiki/Acceleration

    The acceleration of a falling body in the absence of resistances to motion is dependent only on the gravitational field strength g (also called acceleration due to gravity). By Newton's Second Law the force F g {\displaystyle \mathbf {F_{g}} } acting on a body is given by: F g = m g . {\displaystyle \mathbf {F_{g}} =m\mathbf {g} .}

    Acceleration – In physics, acceleration is the rate of change of velocity of an object with respect to time. An object's acceleration is the net result of any and all forces acting on the object, as described by Newton's Second Law. [5] The SI unit for acceleration is metre per second squared (m s −2).
