# Ch 3: AP Physics C: Acceleration, Velocity, & Gravity

### About This Chapter

## AP Physics C: Acceleration, Velocity & Gravity - Chapter Summary

Our instructors explain detailed concepts related to gravity, acceleration, and velocity to help you prepare for the AP Physics C - Mechanics exam. The lessons in this chapter review key topics you could encounter on test day, including finding slope in position vs. time graphs, describing motion through velocity vs. time graphs, and projectile motion. By the end of this chapter, you should be able to:

- Create and interpret various graphs of motion
- Determine the acceleration and displacement of an object
- Understand how to use velocity as a measure of speed and direction of motion
- Solve problems related to free falling objects due to gravity
- Describe the acceleration of gravity
- Define projectile motion
- Explain kinematic equations

This course is self paced, giving you the ability to learn at your own comfort and speed. The lessons have been specially developed to keep you engaged in the review process to help you take the AP Physics C - Mechanics exam with confidence! After watching each lesson, make sure to take the self-assessment quiz to determine your understanding and see if you are ready to move on to the next concept.

### 1. 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.

### 2. 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.

### 3. 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.

### 4. 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.

### 5. 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.

### 6. 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.

### 7. 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.

### 8. 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.

### 9. 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.

### 10. 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.

### 11. 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.
