Velocity and Acceleration in Three Dimensions
The position of a particle can be described by a position vector, which is a vector extending from the origin to the particle. We can write it in component form as
r = x^ i y^ j ^ z k

Base Units and Derived Units
Standards are associated with base units, and measurement of a physical quantity takes place by comparison with a standard. We will mostly use SI units (the name comes form the French: Systme
Notes on Chapter 2
Velocity and Speed
The position of an object is denoted by its coordinate x(t) along an axis, on which we have defined an origin (the point defined as x = 0). As the body moves, its coordinate changes and hence x is a function of t

Vectors
To describe motion in three dimensions we will use vectors. A vector has magnitude and direction. An example of a vector quantity is displacement. The displacement of a particle which moves from point A to point

Overview
Objects may interact with each other and their velocities change as a result. The strength of an interaction depends on properties of the objects and their relative positions. Gravitational mass is responsible for gravitat

Friction
Consider applying a small horizontal force to a massive block placed on a tabletop (refer to the figure at right). Unless the force is greater than a certain critical force the box will not move. This is because a friction
