In physics, moment describes the rotational effect of a force on a body about a fixed point or axis. For example, when a door is pushed open, a moment force is being applied onto it, causing it to rotate about an axis (hinges). The angle that which the force is applied to the door...

but the specific definition physics uses is something different. Specific impulse is the amount of impulse distributed over the weight of an object. In fact, whenever the termspecificis used with quantities in physics, it means ''divide by mass or weight.'' Physicists do this to simplify calcu...
The2nd moment around the mean = Σ(xi– μx)2. This is equal to thevariance. The Σ symbol means to “add up”. See:What is sigma notation?In practice, only the first two moments are ever used in statistics. Several more moments are common in physics: ...
