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.
Try to get into the habit of brushing your baby's teeth twice a day. Do it once in the morning, at a time that fits in with your usual routine (BDHF nd, NHS 2014d, PHE 2014). The second clean should be before bed, after your baby's had his last drink (NHS 2014d).
