Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. The symbol for torque is typically formula_1, the lowercase Greek letter "tau". When being referred to as moment of force, it is commonly denoted by "M". In three dimensions, the torque is a pseudovector; for point particles, it is given by the cross product of the position vector (distance vector)
Kra (letter) Kra (letter) Kra (Kʼ / ĸ) is a glyph formerly used to write the Kalaallisut language of Greenland and is now only found in Nunatsiavummiutut, a distinct Inuktitut dialect. It is visually similar to a Latin small capital letter "K" and the Greek letter kappa "κ".
