Khan Academy: Optimal Angle for Projectile Part 4: Optimal Angle and Distance

Angry Birds prepared them, but now pupils must prove their skills with projectiles! Scholars test different variables to determine which ones impact the distance the projectile flies. The experiment provides connections to kinetic and...

As a follow up to the Kahn Academy video on parallax, this video focuses on parallax as it relates to astronomical distance. Sal uses cardinal directions and the seasons to orient students in the proverbial night sky. After providing a...

Have you ever wanted to shoot someone out of a canon? This simulation gives you that chance! In addition to a human, you can shoot a car, a piano, a cannon ball, and many other items. Scholars set the angle, initial speed, mass, air...

Horizontal and vertical speeds change as projectiles move through space. As part of a series on vectors and projectiles, scholars create vector diagrams to compare these speeds at various locations. They they determine the values for...

Examine harmonic motion by using your knowledge of calculus with this video. [9:45]

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. 

Sal Khan speaks to race car driver JR Hildebrand about the optimal turns at Indianapolis Motor Speedway. [6:24]

Two-Dimensional motion giving you a headache? Then watch this video lecture to help with visualizing, adding and breaking down vectors in two dimensions. Lecture includes examples and step-by-step problems. [12:53]

Eight problems require general physics recruits to calculate acceleration or distance traveled. They read the situations involving cars and buses, running bears, downhill skiers, and a rock slide and then get to work. Provide this as a...

The sun will continue to rise in the east and set in the west, no matter what. The first lesson in a series of eight introduces the class to solar angles. It makes connections between a person's latitude and the angle of position of the...
