The PhET:Projectile Motion Activity Guide is used along with the free *Next Generation PhET Simulation on Projectile Motion. Students learn how the motion of a projectile is affected by changes in the initial height, initial speed, cannon angle, and other variables with or without the affects of wind resistance. This activity guide follows closely with the newest (HTML5) version of the PhET Projectile Motion simulation. Your students will hit the ground running without the need for a le
