Albin Jr.[/color] Professional Educator [url]www.donaldalbin.99k.org[/url] [b]Preliminary Questions:[/b] [list] [*]When you throw a baseball, how do you make sure the ball reaches your teammate? [*]If you're throwing to home place, how do you throw a ball differently whether you are in the outfield or on first base? [*]When hunting with a rifle or bow-and-arrow, how do you hit your target? [*]How is the projectile motion in hunting different from the projectile motion in baseball? [/list] Projectiles, such as balls, arrows, and rockets, are quite common to the human experience. Do you ever throw a baseball, play tennis, target shoot, or hunt for game? There are many factors that affect the flight of projectiles. This simulation will help you investigate projectile motion.
[b]Questions to promote inquiry:[/b] [list] [*]Can you make the ball fly exactly 500 feet? What factors affect the flight distance? [*]How could you account for wind resistance? Is wind resistance different than wind speed? [*]What if you were on the moon (gravity ~ 5.34 ft/s²)? [*]What equations and boundary conditions help you calculate projectile motion? [/list] [b]Directions[/b] [list] [*]Adjust the factors to see how the motion is affected. [*]You may adjust the launch vector 'v0', the launch height 'y0', and the accelerations 'a' in the y- and x-directions. [*]To see the projectile actually move, drag the slider labeled 't' to the left, then release. [/list]
