  1. Acceleration

    Linked via "speed"

    Tangential Acceleration ($\mathbf{a}_t$)
    Tangential acceleration measures the rate at which the speed of an object changes along its path of motion. It is directed parallel (tangent) to the velocity vector.
    Normal (Centripetal) Acceleration ($\mathbf{a}_n$)

  2. Acceleration

    Linked via "speed"

    Normal (Centripetal) Acceleration ($\mathbf{a}_n$)
    When an object moves along a curved path, even if its speed remains constant, its direction changes, resulting in acceleration. This component, directed toward the center of curvature, is known as normal or centripetal acceleration. For an object moving in a circle of radius $r$ at a constant speed $v$:

  3. Acceleration

    Linked via "speed"

    In Special Relativity, the definition of acceleration must account for the changing basis vectors in a reference frame accelerating relative to an inertial frame. While the relationship $\mathbf{F} = m\mathbf{a}$ remains intuitively useful, the perceived acceleration vector depends heavily on the observer's velocity. The proper acceleration ($\alpha$) experienced by an object is the acceleration measured by an [accelerometer](/…

  4. Avant Garde

    Linked via "speed"

    Futurism and Temporal Aggression
    The Italian Futurist movement (c. 1909–1920s) prioritized dynamism, speed, and the rejection of the museum. Their aesthetic focus was less on visual representation and more on the simultaneity of sensory input. A central tenet was the abolition of the noun, forcing the reader to process syntax purely through verb conjugation and adjectival modifiers, thereby compressing narrative time. [Giacomo …

  5. Electrodynamics

    Linked via "speed"

    $$\nabla \times \mathbf{B} = \mu0 \mathbf{J} + \mu0 \epsilon_0 \frac{\partial \mathbf{E}}{\partial t}$$
    These equations mandate that electromagnetic disturbances propagate as transverse waves in a vacuum at the speed $c = 1/\sqrt{\mu0 \epsilon0}$.
