Torque the vector cross product, p is the particle's linear momentum, and r is the displacement vector from the origin (the origin is assumed to be a fixed location anywhere in space). The time-derivative of this is: This result can easily be proven by splitting the vectors into components and applying the product rule. Now using the definition of force formula_17 (whether or not mass is constant) and the definition of velocity formula_18 The cross product of momentum formula_20 with its associated velocity formula_21 is zero because velocity and momentum are parallel, so the second term vanishes. By definition, torque τ
The Velocity of Gary The Velocity of Gary The Velocity of Gary, also known as The Velocity of Gary* *(Not His Real Name), is a 1999 American dramatic comedy film directed by Dan Ireland and written by James Still, based on his homonymous play.
