Khan Academy: Two Dimensional Projectile Motion: Unit Vector 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]

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

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

Projectile motion problems got you scratching your head? This video walks you through figuring out the horizontal displacement for a projectile launched at an angle. [12:46]

The challenging problem of a projectile on an inclined plane is discussed.

Projectile motion problems still confusing you? This video lecture walks you through an example of a two-dimensional projectile motion problem. The problem shows you another way to determine time in the air given an initial vertical...

Solve a collision of balls in two dimensions using the conservations of momentum in this video. Video discusses how specifically to use trigonometry to solve the direction and velocity of the balls after the collision. [9:32]

A video explaining how acceleration is change in velocity over time. Video also includes examples of how to solve for the vector quantity of acceleration. [9:05]

Learn how a car traveling at a constant speed around a curve is actually accelerating. This video explains how acceleration not only involves a change in speed but also a change in direction. [4:49]
