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.
Mouthrinses and mouthwashes are not intended to replace tooth brushing. It is important to brush your teeth twice a day with a fluoride toothpaste. One of those times should be before going to bed to remove all food particles from teeth and prevent the length of attacks by food on teeth. Using a rinse after brushing can help freshen breath and prevent tooth decay.
