  2. Power of 10 - Wikipedia

    en.wikipedia.org/wiki/Power_of_10

    Power of 10. Visualisation of powers of 10 from one to 1 trillion. A power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten are:

    G {\displaystyle G} electrical conductance. siemens (S) universal gravitational constant. newton meter squared per kilogram squared (N⋅m 2 /kg 2 ) shear modulus. pascal (Pa) or newton per square meter (N/m 2 ) g {\displaystyle \mathbf {g} } acceleration due to gravity.

  4. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). Pilots of high-altitude aerospace vehicles use flight Mach number to express a vehicle's true airspeed , but the flow field around a vehicle varies in three dimensions, with corresponding variations in local Mach number.

  5. Engineering notation - Wikipedia

    en.wikipedia.org/wiki/Engineering_notation

    Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).

  7. Jerk (physics) - Wikipedia

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

    Design standards for high-speed rail vary from 0.2 m/s 3 to 0.6 m/s 3. [4] Track transition curves limit the jerk when transitioning from a straight line to a curve, or vice versa. Recall that in constant-speed motion along an arc, acceleration is zero in the tangential direction and nonzero in the inward normal direction.

    en.wikipedia.org/wiki/Exponentiation

    Graphs of y = b x for various bases b: base 10, base e, base 2, base ⁠ 1 / 2 ⁠. Each curve passes through the point (0, 1) because any nonzero number raised to the power of 0 is 1. At x = 1, the value of y equals the base because any number raised to the power of 1 is the number itself.
