Most students play sports. And when they become old students, they enjoy watching sports. Many sports involve throwing or kicking a ball and all sports are played within the Earth's atmosphere. So aerodynamic forces play a major role in many sports. We have devloped several software packages to help students better understand, explore, and visualize the aerodynamic and gravitational forces that act on a ball in flight. These forces affect the motion of the ball according to Newton's laws of motion. A ball in flight is exactly like a gliding aircraft in flight.

CurveBall Student Using the CurveBall Student applet, students learn more about aerodynamics by controlling conditions of a big league baseball pitch. The parameters that affect the flight of the ball include stadium location and weather conditions, which affect the air density, speed of the pitch, and spin on the ball. You set the conditions for the pitch using the input boxes, sliders, and choice boxes on the program display. CurveBall Student version is a two dimensional simulation that neglects the effects of gravity and drag on the ball. As the ball travels from the pitcher to home plate, the ball can only move side-to-side under the actions of the aerodynamic force. To better understand what is happening to the ball, we include a "Wind Tunnel View" of air passing the ball.. A probe is provided so that the student can see the change in velocity and pressure around the spinning ball.

3. Go to the directory where you have stored "FoilSimb.zip" and open the "WinZip" program.
4. "Extract" all the files. If you skip this step, you will only see a grey box when you try to run CurveBall.
5. Click on either Ball.html or FoilSimb.html to launch your browser and load the driver program. Ball.html is intended for experienced users and only displays the program; FoilSimb.html includes instructions on program operation.

CurveBall Expert Using the CurveBall Expert applet, students can learn even more about the motion of a big league baseball pitch. The Expert version includes all of the the effects of the Student version plus the effects of gravity and drag on the pitch. CurveBall Expert is a three dimensional simulation, so there are some additional input factors that the user must specify before throwing a pitch. The output also includes multiple views to help the student visualize the movement of the ball in all three dimensions.

3. Go to the directory where you have stored "BallKiosk.zip" and open the "WinZip" program.
4. "Extract" all the files. If you skip this step, you will only see a grey box when you try to run CurveBall.
5. Click on either Ball.html or Ballk.html to launch your browser and load the driver program. Ball.html is intended for experienced users and only displays the program; Ballk.html includes instructions on program operation.

HitModeler Student Using the HitModeler Student applet, students can learn about the motion of a hit baseball. The parameters that affect the flight of the ball include stadium location and weather conditions, which determines the air density, speed and angle of the ball leaving the bat, wind direction and wind speed, and the drag coefficient of the ball. You specify the values for the input parameters using the input boxes, sliders, and choice boxes on the display. There is a simplified version of HitModeler that only accepts slider and choice box inputs for younger stduents. HitModeler Student version is a two dimensional simulation that includes the effects of gravity and drag on the ball. Output includes the trajectory of the ball, and a running calculation of the time and location of the ball in flight. The game can be moved to the Moon or Mars with this software.

4. Go to the directory where you have stored "Hit.zip" and open the "WinZip" program.
5. "Extract" all the files. If you skip this step, you will only see a grey box when you try to run HitModeler.
6. Click on Hit.html to launch your browser and load the driver program.

HitModeler Weather Using the HitModeler Weather applet, students can learn about how the weather affects the motion of a hit baseball. The Weather version of the applet was built for younger students who might find all of the options in the Student version to be too confusing. All of the inputs to the Weather version are made with the buttons at the lower part of the program. HitModeler Weather version is a two dimensional simulation that includes the effects of gravity and drag on the ball. The ball is launched at 100 mph at 45 degrees to the horizontal. Output includes the trajectory of the ball, and a running calculation of the time and location of the ball in flight.

3. Go to the directory where you have stored "WHit.zip" and open the "WinZip" program.
4. "Extract" all the files. If you skip this step, you will only see a grey box when you try to run HitModeler.
5. Click on WHit.html to launch your browser and load the driver program.

SoccerNASA Using the SoccerNASA applet, students can learn about the motion of a kicked soccer ball. SoccerNASA lets you control the value of all the parameters that affect the flight of soccer kick. You can choose a penalty kick, a free kick, or a corner kick. You select the stadium location and weather conditions that determine the air density, speed of the kick, and spin on the ball. You can also vary the lift and drag coefficients and the location of a free kick. All of the input conditions are set using the input boxes, sliders, choice boxes, and buttons on the display. The objective is to put the ball in the net. You can play the game at any of the stadium locations from the 2010 World Cup. Output includes multiple views to help the student visualize the movement of the ball in all three dimensions.
