its not clinical and i would ask your doc before doing it but for me double rubber bands worked well.
Velocity is said to have changed when either the speed or the direction of motion changes. There are myriads of things that can cause it, including jets, rubber bands, gravity, and friction.
You need to do exactly as your dentist tells you to do. Make sure to keep your rubbers bands on.
Though uncomfortable and often painful, braces serve the purpose of straightening teeth. This process is done by a person called an orthodontist. The orthodontist specializes in everything involving braces and retainers. Most people who have braces are only subjected to them for a couple years. Head gear and rubber bands are couple of mechanisms that are used to speed up the braces process. Depending on how crooked a person's teeth are, braces can be on anywhere from one year to four years. The best way to reduce that time is to follow the orthodontist's instructions on how to maintain braces. A simple way to keep teeth healthy and happy is simply to brush and floss often. If you do this, your experience with having a metal mouth will most likely be no big deal!
yes of course
The speed.
The acceleration changes if speed or direction changes
Velocity is speed in a direction or speed at an angle. The velocity changes when the speed or angle changes.

Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
