 Objectives:

After reading an explanation from a NASA Web site, you will demonstrate an understanding of the text by applying it to questions involving the Thrust to Weight Ratio and Excess Thrust of an aircraft.

The Beginner's Guide to Propulsion is a Web site of information prepared at NASA Glenn Research Center to help you better understand propulsion. Open the slides called Thrust to Weight Ratio and Excess Thrust and read the explanations relating to these two scientific concepts. Use these descriptions as background information to help you complete the activity.

Assessment:

You, or you and your partner(s), will be evaluated on the accuracy and feasibility of your answers.

Evaluation:

You will demonstrate the ability to use information found on the World Wide Web and complete questions which involve the Thrust to Weight Ratio as well as Excess Thrust.
