Momentum, Kinetic Energy, and Arrow Penetration
... To understand the relationship between an arrow’s kinetic energy, its momentum, and their implications towards the ability of a hunting arrow to penetrate tissues, one must rely on the laws of physics. This discussion cannot be made totally uncomplicated. The following is an attempt to impart a fund ...

Vector Calculus - New Age International
... Since dR/du is itself a vector depending on u, if its derivative with respect to u exists, then it is denoted by d2R/du2. Similarly, higher order derivatives may be defined. If r = xi + yj + zk, is the position vector of a moving particle P (x, y, z) in space, then, dr = dx i + dy j + dz k ...

chapter 3 part 1
... Every object continues in a state of rest , or of uniform motion in a straight line , unless it is compelled to change that state by forces acting upon it. An equivalent statement of the first law is that : An object at rest will stay at rest, and an object in motion will stay in motion at constant ...
