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!

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

- 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
- Solve conceptual/numerical/relationship problems involving objects having constant velocity or speed.
- Solve conceptual/numerical/relationship problems involving objects having constant non zero acceleration.
- Calculate, identify, and interpret unknown quantities given a position-time graph.
- Calculate, identify, and interpret unknown quantities given a velocity-time graph.
- Calculate, identify, and interpret unknown quantities given an acceleration-time graph.
- Given the shape of a displacement/velocity/acceleration graph, redraw the same motion on a different type of graph.

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!**
