In Equation (1-97), i, j, and k respectively are unit vectors along the x, y, and z coordinate axes; u, v, and w are the three velocity components on the x, y, and z axes. They can be expressed as in the following functions: (1-98)u=u(x,y,z,t)υ=υ(x,y,z,t)ω=...
1.3 VECTORS AND DIRECTIONS Force, momentum, velocity and acceleration are examples of vector quantities (they have a direction and a magnitude) and are written in this book with an arrow over them. Other physical quantities (for example, mass and energy) which do not have a direction will be...
Scalars and Vectors Distance and Displacement Speed and Velocity Acceleration Just as distance and displacement have distinctly different meanings (despite their similarities), so do speed and velocity. Speed is a scalar quantity that refers to "how fast an object is moving." Speed can be thou...

The numerical information in both the diagram and the table above illustrate identical points - a projectile has a vertical acceleration of 9.8 m/s/s, downward and no horizontal acceleration. This is to say that the vertical velocity changes by 9.8 m/s each second and the horizontal velocity ...
The graph that explains velocity against time is known as the Velocity-time graph. This explains how the velocity changes following time. The slope of a Distance time graph uniform velocity regulatesacceleration. In a distance-time graph, let us consider three objects as A, B, C, and all th...

The last one — impact or diffused droplet region is the area of abrupt flow deacceleration and turning into parallel to workpiece surface direction. Inside potential core, air velocity is higher than that of the particle, thus the particle preserves its acceleration until it becomes faster than ...
At the onset of motion, the velocity is very low and the two velocity-dependent terms in Eq. (9.67) can be neglected. This means that the initial velocity and acceleration are along the J×Φ0 or x direction. As motion continues the velocity v(t) increases in magnitude toward a terminal...
