  2. Model rocket motor classification - Wikipedia

    en.wikipedia.org/wiki/Model_rocket_motor...

    The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...

  3. Newton-metre - Wikipedia

    en.wikipedia.org/wiki/Newton-metre

    The newton-metre or newton-meter (also non-hyphenated, newton metre or newton meter; symbol Nm [1] or N m [1]) [a] is the unit of torque (also called moment) in the International System of Units (SI). One newton-metre is equal to the torque resulting from a force of one newton applied perpendicularly to the end of a moment arm that is one ...

    The graphs below show the angle domain equations for a constant rod length (6.0") and various values of half stroke (1.8", 2.0", 2.2"). Note in the graphs that L is rod length l {\displaystyle l} and R is half stroke r {\displaystyle r} .

  5. Impulse (physics) - Wikipedia

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

    m is the mass of the object, v 2 is the final velocity of the object at the end of the time interval, and; v 1 is the initial velocity of the object when the time interval begins. Impulse has the same units and dimensions (MLT −1) as momentum. In the International System of Units, these are kg⋅m/s = N⋅s.
