PHYS 1111 - Introductory Physics I
Chapter 3 - Vectors and Two-Dimensional Motion

Study Assignment:

Chapter 3, Sections 3.1 - 3.5

Lesson notes:

This chapter provides the mathematical background necessary to manipulate vector quantities. The ability to express a vector quantity in component form is an essential skill required for success in the course. In this chapter we will extend the definitions of velocity and acceleration to two dimensions. This extension into more than one dimension requires the use of vectors to describe both the magnitudes and directions associated with velocity and acceleration. 

Objectives:

1. Be able to express a vector as a magnitude and direction, in components, and in terms of unit vectors, and be able to convert between the three forms.

2. Be able to add and subtract vectors graphically and algebraically.

3. Be able to multiply a vector by a scalar.

4. Understand the definitions of displacement, average velocity, velocity, average acceleration and acceleration in two-dimensional motion.

Vocabulary:

vector
scalar
triangle method of addition
parallelogram method of addition
