- Change in atmospheric pressure as rocket ascends.
- Acceleration of rocket.
Use collected data to:
-Identify maximum height attained by rocket.
-Identify maximum acceleration of rocket.
- Compare these results to simulation data.
Additional Features:
-On/Off indicatior for charge of battery.
-Audible component to aid in retrieval of rocket.]]> 2021-05-12 09:16:05 UTC https://padlet.com/prasunshrestha1/l9vtn1arx5w456zu/wish/1516796892 joshuaogamba2 https://padlet.com/prasunshrestha1/l9vtn1arx5w456zu/wish/1516807584 - Payload size (should be able to fit inside model rocket).
- Payload weight (should be minimized to allow for rocket to achieve largest possible maximum height).
      --> Knowing that each engine can lift a maximum weight of 10 ounces (283.5g). Taking into account that each engine package have two engines, they can lift a maximum weight of 20 ounces (567 grams). And the weight of both engine combined is already of 91.2 grams.
     --> So the rest of the rocket can maximum weight 475.8 grams.
