SpletRoller Coaster Model. This interactive simulation allows students to explore energy and forces associated with the motion of a roller coaster car. The model window represents the forces (Fgrav and Fnorm) the velocity by vector arrows and represents kinetic energy, potential energy, and the total mechanical energy by bar charts. Phosphate-buffered saline (PBS) is a buffer solution (pH ~ 7.4) commonly used in biological research. It is a water-based salt solution containing disodium hydrogen phosphate, sodium chloride and, in some formulations, potassium chloride and potassium dihydrogen phosphate. The buffer helps to maintain a constant pH. The osmolarity and ion concentrations of the solutions match those of the human body (isotonic). shortest daylight day
