### 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. 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.

### 4. 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.

### 5. 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.

### 6. 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.

### 7. 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.

### 8. 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.

### 9. 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.

### 10. 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.

### 11. 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.

### 12. 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.

### 13. 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.

### 14. 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.

### 15. Free Fall Physics Practice Problems

In this lesson, we will dive into doing calculations involving free falling objects. We will begin with a few helpful tips to get started before working through a couple of example problems.

### 16. Graphing Free Fall Motion: Showing Acceleration

Kinematics topics are great for using x, y scatter graphs to visualize motion. In this lesson, we will examine the basic shapes of two different types of graphs of an object in free fall.

### 17. The Acceleration of Gravity: Definition & Formula

In this lesson, we will introduce the acceleration due to gravity. Objects in free fall are one of the few real world examples of straight line motion with constant acceleration, so they are commonly used when learning kinematics.

### 18. Projectile Motion: Definition and Examples

A projectile is any object that is given an initial velocity and then follows a path determined entirely by gravity. In this lesson, we will introduce projectile motion and touch on a few key facts to keep in mind when working through these problems.

### 19. Projectile Motion Practice Problems

After watching this video lesson, you will know how to use the sets of equations that are used to solve projectile motion problems. Learn how to manipulate them to find the answer you need.

### 20. Kinematic Equations List: Calculating Motion

After watching this video, you will be able to explain what kinematics is, list the five most important kinematics equations, and use them to solve problems. A short quiz will follow.

### 21. Solving Kinematics Problems

How do we use physics to answer questions about motion? One way is with kinematics, and in this lesson we'll examine several kinematics equations and how to use them.
