Khan Academy: 2 D Projectile Motion: Unit Vectors and Engineering Notation

A unique and useful presentation, this covers projectile motion for your general physics class. Many graphs display the vectors involved, and some even act as animations. Motion is broken down into its components and only then are the...

Continues from an earlier video on unit vector notation. Demonstrates that adding the x and y components of two vectors is equivalent to adding the vectors visually using the head-to-tail method. [9:13]

Match graphs with the correct scenario for the projectile motion by understanding velocity, acceleration, and displacement.

Learn how to add the components of vectors with this video lecture. Step-by-step solutions to these types of problems are given. [9:53]

Reconstructing the total displacement vector for a projectile. [13:46]

Explains how to calculate the total final velocity for a projectile landing at a different altitude. (There is a mistake near the end where Sal wrote 29.03 m/s when it should be 26.03 m/s, and the final total magnitude should be 26.55...

Practice problems dealing with displacement, velocity, and acceleration vectors for horizontally launched projectiles. In these practice problems, students will compare initial speed and time in the air for multiple projectiles.

Using unit vectors to represent the components of a vector. [7:58]

Hit a bullseye with an engaging presentation about the components of projectile motion. Viewers see how horizontal and vertical motion combine to create the parabolic path of projectile motion. 

A more complicated example of two-dimensional projectile motion involving launching and landing at different elevations.
