Submitted by Mr. Donald C. Albin Jr. Professional Educator www.donaldalbin.99k.org Preliminary Questions:
- 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?
Questions to promote inquiry:
- 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?
- 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.
