# Ch 2: AP Physics C: Kinematics

### About This Chapter

## AP Physics C: Kinematics - Chapter Summary

Get an introduction to kinematics with the video lessons included in this chapter. Instructors begin by describing what kinematics is and how to study the motion of objects. You can practice calculating acceleration, velocity and displacement, and explore the uses of graphs and diagrams to describe these vector quantities. The video lessons in the chapter, are created by our expert instructors to prepare you for the exam. Access the lessons at any time and on any device. Check your progress using the short quizzes. Lessons are designed to assist you in understanding the following areas of the AP Physics C exam:

- Defining scalars and vectors
- Understanding distance, displacement, speed, velocity and acceleration
- Exploring significant figures and scientific notation
- Utilizing the big five kinematics equations
- Analyzing ticker tape and vector diagrams
- Determining slope for position vs. time graphs
- Understanding position in physics
- Explaining the coordinate system in geometry
- Analyzing motion with ticker tape diagrams

### 1. What is Kinematics? - Studying the Motion of Objects

Kinematics is the study of the motion of objects. Kinematics can tell you a lot about motion, but not everything. In this lesson, we will examine the types of questions kinematics can and cannot answer.

### 2. Scalars and Vectors: Definition and Difference

In this lesson, we will examine scalars and vectors, learn why it is important to know the difference between the two and why remembering to add a direction to many of your exam answers could be the reason you get it right or wrong.

### 3. Coordinate System in Geometry: Definition & Types

Coordinate systems use 1-dimensional, 2-dimensional and 3-dimensional spaces and coordinates to define points. The ''xy'' coordinate grid is the most common of these systems, which you can learn how to use in this lesson.

### 4. What is Position in Physics? - Definition & Examples

After watching this video, you will be able to explain what position is, why it is a vector, and interpret position-time graphs. A short quiz will follow.

### 5. Distance and Displacement in Physics: Definition and Examples

Distance and displacement might seem like similar terms but in physics, understanding the difference can mean getting a question right instead of wrong. In this lesson, we will define these terms and illustrate how easy it is to confuse the two.

### 6. Speed and Velocity: Difference and Examples

Is it possible to drive with a speed of 100 mph but a velocity of 0? In this lesson, we will examine the difference between speed and velocity and use that information to answer this question.

### 7. Acceleration: Definition, Equation and Examples

Acceleration can be a tricky topic for many students who tend to get hung up on an object's speed. In this lesson, we will explore the common aspects of acceleration and why speed is not always important.

### 8. Significant Figures and Scientific Notation

Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.

### 9. 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.

### 10. Representing Kinematics with Graphs

In this lesson, we will introduce how to use graphs to visually represent kinematics. For some students, graphing these types of problems is easier than using algebra equations.

### 11. 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.

### 12. What are Vector Diagrams? - Definition and Uses

After watching this video, you will be able to explain what vector diagrams are and how they are used, including vector addition and subtraction. A short quiz will follow.

### 13. 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.

### 14. 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.
