and the cross-product is a pseudovector i.e. if r and p are reversed in direction (negative), L is not. In general I is an order-2 tensor, see above for its components. The dot · indicates tensor contraction. Force and Newton's 2nd law: Resultant force acts on a system at the center of mass, equal to the rate of change of momentum:

Reference notes. A reference card or reference sheet (or quick reference card) or crib sheet is a concise bundling of condensed notes about a specific topic, such as mathematical formulas [1] to calculate area/volume, or common syntactic rules and idioms of a particular computer platform, application program, or formal language.
r = position from aperture diffracted from it to a point α 0 = incident angle with respect to the normal, from source to aperture α = diffracted angle, from aperture to a point
This list of mathematical series contains formulae for finite and infinite sums. It can be used in conjunction with other tools for evaluating sums. Here, is taken to have the value
Thin cylindrical shell with open ends, of radius r and mass m. = [1] The expression ″thin″ indicates that the shell thickness is negligible. It is a special case of the thick-walled cylindrical tube of the same mass for r 1 = r 2. Solid cylinder of radius r, height h and mass m.
