Predictions

  1.   What where some of the biggest challenges with your construction?  Our groupʻs biggest challenge for this bottle was choosing the right materials in order to construct a strong bottle. 
  2. What factors did you take into consideration regarding the construction of you rocket (i.e. mass, shape of fins, parachute, etc)  We decided to allow the bottle to spin.  By putting the wings in a slight angle to the left, we believe the bottle will give a spin that will affect the air time of the rocket bottle.  
  3. Make a prediction about how your rocket will perform next week.  We predict that the bottle will be as good as we have worked on it.  There may be some flaws to it, but for a starter, it should be able to launch successfully.

Welcome to Bernel, Mika, and Meaghanʻs Blogspot

  1. pressure-the exertion of force upon a surface by an object, fluid, etc., in contact with it
  2. psi- pounds per square inch
  3. center of mass- the point at which the entire mass of a body may be considered concentrated for some purposes;
  4.  propulsion-the act or process of propelling
  5.  Newtonʻs 1st Law- An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by another force
  6.  Newtonʻs 2nd Law- The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.
  7.  Newtonʻs 3rd Law- For every action, there is an equal and opposite reaction
