Explain why the velocity and acceleration vectors behave as they do for the preset motions (linear acceleration I, II, circular motion, & harmonic motion).
Dentist Tip: Brushing three times a day is ideal. If you can brush once after every mealâbreakfast, lunch, and dinnerâyou minimize the growth of bacteria in your mouth. But wait an hour after each meal: brushing too soon can cause damage to the enamel of your teeth.
First thing in the morning, before eating or brushing your teeth: 1  Take about a tablespoon of edible oil (such as olive, sesame, coconut, or sunflower oil). 2  Put it in your mouth without swallowing. 3  Swish it around for 10-15 minutes while doing your other bathroom business.  At the end of the 10-15 minutes, spit it out.
