Solving Motion Problems - Chapter Summary
This chapter simplifies the process of solving motion problems. Review fun lessons to better understand ticker-tape diagrams, graphs of motion, the big five kinematics equations and more. Watch the lessons as short videos, or access them as written transcripts that you can print or read online. If you want to revisit key topics within the lessons, use the clickable timelines found below the videos. Short quizzes and a practice exam can assess your comprehension of the chapter's contents. Once you've completed the lessons, you should be able to:
- Understand uniformly-accelerated motion and the big five kinematics equations
- Use graphs to represent kinematics
- Define a ticker-tape diagram and understand how to analyze motion and acceleration
- Use position vs. time graphs to describe motion
- Determine slope for position vs. time graphs
- Utilize velocity vs. time graphs to describe motion
- Determine acceleration by utilizing the slope of a velocity vs. time graph
- Determine displacement of an object
- Give qualitative descriptions using graphs of motion
1. Uniformly-Accelerated Motion and the Big Five Kinematics Equations
In this lesson, we will begin to solve problems that combine position, displacement, velocity, and acceleration. I will introduce the Big Five Equations to help you on your way.
2. Ticker Tape Diagrams: Analyzing Motion and Acceleration
After watching this video, you will be able to explain what a ticker tape diagram is and analyze motion using a ticker tape diagram. A short quiz will follow.
3. Using Position vs. Time Graphs to Describe Motion
Describing motion with graphs can be a simple, yet powerful tool in your physics arsenal. In this lesson, we begin by looking at the basic position vs. time graph.
4. Determining Slope for Position vs. Time Graphs
Simply looking at a position vs. time graph can tell you a lot about straight line motion, but doing a few basic calculations can tell you even more. In this lesson, we will learn how to use the slope of the line to determine average velocity.
5. Using Velocity vs. Time Graphs to Describe Motion
In this lesson, we will look at an example of a velocity vs. time graph. By examining the shape of the graph, it is possible to accurately describe the motion of an object, even if that motion is very complex.
6. Determining Acceleration Using the Slope of a Velocity vs. Time Graph
In this lesson, we will learn how to use the slope of the line on a velocity vs. time graph to calculate the acceleration of an object in straight line motion.
7. Velocity vs. Time: Determining Displacement of an Object
There is a lot of information you can determine by looking at a velocity vs. time graph. In this lesson, we will use a little geometry to calculate the displacement of the object represented by the graph.
8. Understanding Graphs of Motion: Giving Qualitative Descriptions
You can just look at graphs of straight line motion and accurately describe how that object is moving. In this lesson, we will investigate the basic shapes the graphs can take and what conclusions you can draw from these shapes.
