Chapter 2
Describing Motion
Chapter 2 Overview
In chapter 2, we will try to accomplish two primary goals.
1. Understand and describe the motion of objects.
Define concepts like speed, velocity, acceleration, and
the difference between them.
Solve problems
Chapter 6
Energy and Oscillations
Conservation of Energy
In this chapter we will discuss one of the most important
and fundamental principles in the universe. Energy is
conserved. This means that in any process, the total
amount of energy after the proces

Momentum and Impulse
Conservation of Momentum
In the last chapter we talked about the fundamental law of
the conservation of energy. In this chapter will introduce
another conservation law: the conservation of linear
momentum. (We usually shorte
Chapter 8
Rotational Motion of Solid Objects
Outline of the Chapter
The concepts in this chapter are very similar to the
concepts we learned in chapters 2 through 7. As we study
this chapter, you should try to relate the concepts to those
in previous chap

Circular Motion, the Planets, and Gravity
Uniform Circular Motion
Uniform circular motion is the
. motion of an object
traveling at a constant (uniform) speed in a circular path.
Because velocity is a vector, with a magnitude and
direction, an

WORK AND ENERGY
PREVIEW
Work is the scalar product of the force acting on an object and the displacement through
which it acts. When work is done on or by a system, the energy of that system is always
changed. If work i
