Module 2—Motion in Two Dimensions

In This Module

 

Lesson 1—Graphical Vector Addition in Two Dimensions

 

In this lesson you will learn how to graphically add two vectors in two dimensions.

 

You will explore the following essential question in this lesson and the accompanying lab:

Lesson 2—Vector Components and Cartesian and Navigational Vector Directions

 

In this lesson you will learn to calculate the magnitude and direction of the sum of two vectors, in two dimensions, when given the magnitudes and direction of the two vectors to be added.

 

You will explore the following essential questions:

Lesson 3—Understanding and Predicting the Motion of a Projectile

 

In this lesson you will explore how independent vertical and horizontal motions can be analyzed with kinematics equations to predict the two-dimensional position and velocity of a projectile at various times.

 

You will explore the following essential question:

Lesson 4—Solving Projectile Problems

 

In this lesson you will learn that in the absence of air resistance, projectile motion of an object can be described as a superposition of two motions—a horizontal motion with constant velocity and a vertical motion with uniform acceleration due to gravity. You will also learn to apply the relevant kinematics equation of motion with constant acceleration or uniform motion to solve projectile problems.

 

You will explore the following essential question.

Module 2 Assessment

 

The assessment for Module 2 consists of four (4) assignments, as well as a final module report.

Module 2 Project: Technology in Sports

 

In Module 2 you will be required to complete a module project that relates how technology has changed sports. Your project can take the form of a speech, letter, report, or multimedia presentation that discusses your findings. You will be asked to complete portions of the project in each lesson.

 

Your final presentation will be graded according to these guidelines.

 

Scoring Rubric for Examples

  1. Poor: The presentation is irrelevant or so scant, overgeneralized, or inaccurate that it indicates a poor or almost complete lack of understanding. It contains major errors or is largely inappropriate.

  2. Limited: The presentation is unfocused or inappropriate, potentially relevant but contains inaccuracies or extraneous detail. It shows an understanding that is confused or oversimplified.

  3. Satisfactory: The presentation is largely relevant but may contain some minor factual errors, or there may be a mixture of relevant and extraneous information. It shows a general understanding of dynamics as it relates to sports.

  4. Proficient: The presentation is purposeful, usually specific, relevant, and accurate, indicating a solid understanding of how dynamics affects sports.

  5. Excellent: The presentation is comprehensive, specific, relevant, and accurate, and it demonstrates a superior understanding of how dynamics affects sports.

Each of the preliminary parts of the project will be graded on a 2-point scale: 0 points if the part shows little or no effort expended, 1 point for some effort, and 2 points if considerable effort is shown.
