### 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. 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.

### 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. Find Displacement: Definition & Equation

In this lesson, you will learn about displacement, the properties associated with it, the equation needed to calculate displacement, and some simple examples of the calculations.

### 5. Speed and Velocity: Concepts and Formulas

Did you know that an object's speed and velocity may not be the same? This lesson describes the concepts of speed and velocity relating to objects in motion. We'll look at a specific example to help learn how to calculate both speed and velocity.

### 6. 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.

### 7. 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.

### 8. Velocity and the Rate of Change

Running from your little sister or just window-shopping, your speed is just a measure of how fast you move, or how your position is changing over time. In this lesson, learn about how velocity is a rate of change.

### 9. Instantaneous Velocity: Definition & Formula

When driving, never take your eyes off the road! That said, it's necessary to occasionally glance at the speedometer. When you do, you are reading your instantaneous velocity. This lesson explores the science behind instantaneous velocity.

### 10. Average Velocity: Definition, Formula & Examples

If we are looking at an object in motion over a period of time, we are able to determine the object's average velocity for any sub-interval of time as well as over the entire period of time. Let's learn more about average velocity in this lesson!

### 11. 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.

### 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. Calculating Deceleration: Definition, Formula & Examples

In this lesson, you will learn about deceleration, what it means, and how it is a specific special case of acceleration. You will learn about which equations can be used to calculate deceleration and how to identify deceleration from position-time and velocity-time graphs of motion.

### 14. Practice Calculating Velocity & Acceleration

Kinematics is the study of motion. In this lesson, we will practice calculating the two types of velocity and acceleration. Also, we will be looking at graphs of displacement vs. time and acceleration vs. time.

### 15. 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.

### 16. 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.

### 17. 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.

### 18. 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.

### 19. Practice Calculating Motion Using Kinematic Equations & Graphs

Motion has many components associated with it. This lesson will tie all of the components of motion together by using the kinematics equations and graphs of motion.
