The explanatory variable or factor in this example will be the type of pain relief drug given to the participants. }^{?} Students conduct an experiment to study the motion of two toy rockets. This can be demonstrated through conservation of energy: At the launch, all the energy is kinetic energy, E0 = K = (1/2) m v02. They maybe able to identify things you have missed. Students conduct an experiment to study the motion of two toy rockets. This is to eliminate the placebo effect so that all participants feel part of the experiment. Student 2 is correct about everything. Fig. For conducting experiment based on effect of a net force , to apply net force on the object two other quantities should be measured in each trial of the experiment is given by velocity and time. Determine what you will test to answer this question. Undergraduate students, graduate students, and faculty. until it reaches its maximum height at time t1. What is the dependent variable that you will measure? If it is not projectile motion, then the equations for max height with appropriate substitutions for vE, hE, and a will need to be made in the original time equation. See more. The maximum height would be the sum of the height to this point and the height in free-fall acting only under gravity. Which is an example of gaining a static charge by conduction?
