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.
Why should I brush my teeth in the morning? My teeth are just going to get dirty again when I eat breakfast 5 minutes later. Plus, I've already done an extensive cleaning (floss, brush, mouthwash) the night before. My teeth should not be getting dirtier as I sleep. I've heard people say their breakfast tastes better after brushing theire teeth. I've never experienced bad taste from not brushing.
