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

The angle at which you launch a rocket plays a role in how far the rocket will go. In this study you will find out whether it is better to launch a rocket along the ground, straight up from the ground, or somewhere in between. Blast off into this investigation!

Here are some definitions to help you in your investigation.

Motion - tells how something changes its position over time

Angle - the amount of turn of something

Degrees - a measure of the size of an angle

0 degrees - flat along the ground

90 degrees - straight up from the ground

Launch - to send off or release something

Distance - how far something moves

Meters - a unit that measures length or distance moved

Cause - something that brings about an action

Effect - a change as a result of an action

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.
