To answer the following questions.

Under 1-D Kinematics Section (Lesson 1: Describing Motion with Words)

Go to Distance and Displacement Section and the Check Your Understanding Section.

Define what Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

Define what Displacement is.

What is the displacement of the cross-country team if they begin at the school, run 10 miles and finish back at the school?

What is the distance and the displacement of the race car drivers in the Indy 500?

Go to Speed and Velocity Section and Open the ANIMATION “button” and

Describe (in your own words) the difference between Average Speed and Instantaneous Speed. 

Go to Acceleration Section and Open the ANIMATION “button” and

Which car or cars (red, green, and/or blue) are undergoing an acceleration? Study each car individually in order to determine the answer.

Consider the position-time graph at the right (graph A, B or C). Each one of the three lines on the position-time graph corresponds to the motion of one of the three cars. Match the appropriate line to the particular color of car.

Under 1-D Kinematics Section (Lesson 2: Describing Motion with Diagrams)

Go to Ticker Tape Diagrams and Read this Section (we will be using Ticker Tapes in Lab #2 so it will help to understand how to calculate Acceleration using Ticker Tapes)

Using the Check Your Understanding Section. Analyze the three traces of Renatta's ventures as shown in the Ticker Tapes. Assume Renatta is traveling from left to right. Describe Renatta's motion characteristics during each section of the diagram.

Under Newton’s Laws Section (Lesson 2: Force and its Representation)

Go to Types of Forces and Read this Section.

Define (Understand each one and be able to compare and contrast) each of the following types of Forces:

Applied Force

Gravitational Force

Normal Force

Frictional Force

Air Resistance Force

Tension Force

Spring Force
