Determines the effects of something previously unconfirmed. Have you ever tried something different or new just to see what would happen as a result? Students could conduct a case study of a person with a particular disorder, such as anxiety or depression, and examine their experiences and treatment options. }{?} B. As the rocket travels upward, frictional forces are considered to be negligible. If it is assumed that the rocket has an engine that exerts a force, F, for some time tE, then the height calculation needs to take into consideration this force. The data collected will be more accurate. The reaction, or motion, of the rocket is equal to and in the opposite direction of the action, or thrust, from the engine (third .

Mass and acceleration A ___________ experiment refers to an experiment where both the subjects and the members of the research team measuring the response to the treatments, are unaware of what treatment the subjects are receiving. You compare results with your peers and find that everyone has different data. Since MR > mR, aY < aX. E0 = Emax ==> K = P ==> (1/2) m v02 = mghmax ==> mass can be canceled from both sides of the equation, so the maximum height is independent of the mass of the rockets and depends only on the initial velocity and acceleration due to gravity, hmax = v02 / (2g).
