Overview

This page provides resources that will help you succeed with one dimensional motion concepts. This is the first unit in physics where you are exposed to a great deal of math concepts. Throughout this unit you will develop new ways to link math and science concepts. This will set you up to be successful for the remainder of the year, so it is critical that you have a decent understanding of this unit! Please review the content on this page as it is added and come in for additional help as often as you need to in order to feel confident in your understanding of 1-D motion!

1-D Motion Objectives

By the end of the 1-D motion unit, you should be able to complete the following objectives:

  1. Define, distinguish, and use correctly the following kinematics terms: distance, displacement, speed, velocity, acceleration, rate, scalar, vector, average speed and average velocity, instantaneous speed and instantaneous velocity, relative motion
  2. Solve conceptual/numerical/relationship problems involving objects having constant velocity or speed.
  3. Solve conceptual/numerical/relationship problems involving objects having constant non zero acceleration.
  4. Calculate, identify, and interpret unknown quantities given a position-time graph.
  5. Calculate, identify, and interpret unknown quantities given a velocity-time graph.
  6. Calculate, identify, and interpret unknown quantities given an acceleration-time graph.
  7. Given the shape of a displacement/velocity/acceleration graph, redraw the same motion on a different type of graph.

1-D Motion Packet Answer Key

1-D Motion Readings

Physics is sometimes thought of as a difficult subject.  The truth is, it will be difficult if you fall behind or do not have the basic knowledge in order to be successful.  Once you have knowledge of topics in physics, you can easily solve problems and understand given situations.  To gain this knowledge, you will have to be attentive and self-directed in class, but also be able to read outside of class as well.  Readings in physics are critical to understanding the material, so please keep up to date!  This cannot be stressed enough!

Describing Motion - Lesson 1

You already describe the motion of everyday objects most likely without even realizing that you are doing so such as when you say things like "I sped up" or "I was stopped at a light". In this unit, you learn to use different terms to describe concepts that you are already familiar with. Please use the link below to read lessons 1a, 1b, 1c, 1d and 1e in 1-D Kinematics. This will prepare you to talk about the motion of objects in this unit.

Diagramming Motion - Lesson 2

It is very important to be able to visualize what is happening in a physics scenario.  Even if you can visualize scenarios very well, it is still important to be able to sketch a basic model of what is happening in a given situation.  Lessons 2a, 2b and 2c (see link below) describe how to do this effectively.

Graphing Motion - Lesson 3/4

Have you ever wondered how some of the equations in physics were thought of? Many were found only after analyzing the results of experiments by graphing.  Many times when people think of physics, they think of a lot of equations. Without being able to graph data, most of these equations would simply not exist. It is therefore a very important skill to be able to interpret graphs well and make sense of how they fit with mathematical expressions. Lessons 3a, 3b, 3c, 4a, 4b, 4c and 4d do an excellent job of explaining what can often be an intimidating concept.

Acceleration from Gravity and Free Fall - Lesson 5

Objects many times do not remain at a consant velocity.  When an object accelerates while moving there are some additional concepts that need to be considered.  Lessons 5a, 5b, 5c, 5d and 5e give a good overview of these additional concepts.
