In the activity, vectors change in real-time as you "drive" a car on a flat plain; as you change speed and direction, vectors originating from the car respond to your actions. A graph depicting speed vs. time also responds to your actions, …

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).
