Learners examine lift, thrust, weight, and drag to gain a better understanding of what each force is and how it relates to the other forces. These basic concepts are used throughout a pilot’s training. This activity has audio content and a quiz.
Determining Empirical and Molecular Formulas (Screencast)
Learners follow a four-step process to determine the empirical formula of a compound from the masses of its constituent elements. The molecular formula is determined in a fifth step using the molecular weight of the compound.
