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.
That is why you want to brush your teeth right after a meal to get rid of the plaque and prevent them from growing. Also, you need to brush not just your teeth, but your gums and tongue as well because germs can grow there too.
