OK ... I found on their website a breakdown by Sections (1,2, etc...) I assume that Section 1 is Chp 1 ??? ...
See below ... Section I:Translational Motion
Top 10 Section Goals
Understand how to work with units and dimensions. The most widely used system of units in the world is the metric system. Physical measurements consist of counting.
Have a working understanding of the difference between scalar and vector quantities. Physical quantities are classified and manipulated according to whether they are scalars or vectors. Scalar quantities have magnitude only. They have no direction in space. Some examples include time, mass, temperature, electric charge, and chemical concentrations. Vectors are quantities that have both magnitude and direction. Some examples of vector quantities include displacement, velocity, acceleration, force, and torque.
Know how to manipulate vectors. Understand how to add, subtract, and multiply vectors; understand that vector components are independent of one another. Know the difference between a dot (a.k.a. scalar or inner) product and a cross (a.k.a. vector or outer) product. The dot product and the cross product are completely different from one another. Know how to apply the right hand rule to a cross product.
Understand the definitions of the sine, cosine, and tangent functions for a right triangle. A right triangle has a hypotenuse, an angle theta, a side opposite to the angle theta, and a side adjacent to the angle theta. Know that Sin (theta) = opposite/hypotenuse, Cos (theta) = adjacent/hypotenuse, and that Tan (theta) = opposite/adjacent.
Be familiar with the three basic types of motion. Translational motion involves the movement of an object from one place to another. Rotational motion examines how an object rotates about an axis. Vibrational motion examines how an object moves back and forth about some central point or axis. In this section, we will primarily be examining translational motion. In later sections, there will be times when we will discuss the combination of translational motion with both rotational and vibrational motion.
Know the difference between speed, velocity, and acceleration. Speed is defined as distance traveled divided by time. Velocity is the rate of change of displacement. Velocity and speed are often confused with one another. Velocity requires the identification of a direction (vector); speed does not (scalar). The dimensions of velocity are the dimensions of length divided by the dimensions of time. The rate of change of velocity with respect to time is referred to as acceleration. The physical dimensions of acceleration are the units of velocity divided by the units of time.
Understand the concepts behind uniformly accelerated motion in the x-direction. In this section we examine the four equations of uniformly accelerated motion. Memorize them! It is important to keep in mind that these four equations are only valid when the acceleration of an object is constant.
Be able to describe a freely falling body. The average acceleration of gravity near the surface of the earth is about 9.8 m/s2 or 32.2 ft/s2. "Average" is used because very precise measurements of the acceleration of gravity will tell us that it is not exactly the same at all locations on the Earth.
Be able to modify the four equations for uniformly accelerated motion in the x-direction. Assuming the gravitational acceleration is constant, one can modify the equations for uniformly accelerated motion in the x-direction to fit uniformly acceleration motion in the y-direction. Understand why it is common when doing problems with these equations to replace "a" with "-g." Know what the minus sign implies.
Know how to solve problems involving projectiles. Be aware that what takes place in the x-direction and what takes place in the y-direction are two independent and separate quantities. Understand how to quickly separate parts of a given problem into a horizontal component and a vertical component.
