Lesson 1: How Does the Launch Angle Affect Rocket Flight?

The angle at which you launch a rocket plays a role in determining how far the rocket will go. In this study you will investigate whether it is better to launch a rocket parallel to the ground (0 degrees), perpendicular to the ground (90 degrees), or somewhere in between. Protractors ready? Launch!

Doing the science

1. Start the Water Rockets Simulation by clicking on the “Simulation” tab.
2. Make the following selections:
   
   
   • Angle: 0°
   • Fluid Volume: 200 mL
   • Pumps: 4
   • Fluid Type: Glycerin
   • Air: Off
   • Wind: Off
   
   
   
3. Click on the “Launch” button.
4. Record the flight distance in meters in Table 1.
5. Click on the “RESET” button.
6. Repeat steps 2-5 increasing only the angle by 10° until you have completely filled out Table 1. Click on the up arrow next to the Angle number two times to increase the angle by 10 degrees.
