This is a short documentary about the designing and building of a catapult for an engineering competition that some students in Kuwait took part in. The first part shows the designing and building followed by 10 min of the theory and calculations beh...ind the design. PowerPoint goes over the steps in their design process as well as the principles and calculations, with video in between. Length (22:31)[more]

Presentation covering a simulation of projectile motion as well as calculations of maximum height and range of a projectile. http://phet.colorado.edu/en/simu...

This 8-minute video introduces the concept of surface tension and shows how roughness can make a surface superhydrophobic or superhydrophilic. The Wenzel and Cassie-Baxter models are explained in this video that uses a variety of images to help expla...in this concept to students. It moves very rapidly and a word wall or handout of terms would be of great value. (08:16)[more]

Mr. Arnold's high school physics class is studying the characteristics of a projectile's trajectory. This video shows his students inside the lab, testing various horizontal and parabolic launched projectiles' velocity using spring-loaded cannons. ...The students then travel outside and continue their observations and calculations by launching rockets in an open field. The WatchKnowLearn team was also there with their cameras and tour bus to help capture the event. (5:40)[more]

There is so much physics in sports! A high school physics teacher goes to Fenway Park during batting practice. He collects data while there and solves a projectile problem. The type of problem he solves can be difficult since the projectile doesn't l...and at the same height as its starting point (06:25).[more]

A high school physics teacher visits a golf course to learn more about projectile motion. He speaks with a golf pro who explains why different clubs are used at different times. It all makes perfect sense when the teacher looks at the range equation ...(06:01)![more]
