The Rocket Demo software includes three simulations and a worksheet that require the use of Newton’s 2nd law and the motion equations. The students are given or allowed to set the mass of the rocket, the thrust of the rocket and asked to calculate the weight, acceleration, velocity, and distance at a given time in the rocket’s ascent. The answers are calculated by the program and can be hidden or shown.
In the first simulation the acceleration of gravity is set at – 9.8 m/sec2. In the second simulation, the acceleration of gravity can be changed. And in the third simulation, the mass of fuel can be set and the fuel mass and weight decreases as the rocket ascends.
There are many more problems and questions than those in the handout that could be asked and solved using the Rocket Demo software.
In the final simulation 3, the fuel and total weight of the rocket are changing with time. Students are asked to think about how predict the height versus chosen thrust. The only way to solve this problem without knowing the nature of the simulation is to take some data. This is included as an Excel file.
All of the files are included in a Zip file. Upzip the files and run the software by double clicking on the RocketDemo.exe file.
