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.
Brushing and flossing twice a day are musts. Start at the gum line (which many people neglect) with the brush tilted at a 45-degree angle, rolling it up and down before moving on to scrubbing the actual biting surfaces of your teeth. When flossing, zigzag the floss between each tooth and go under the gum line.
