The ABEC scale is a system used throughout the manufacturing industry for rating the manufacturing tolerances of precision bearings, developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). Bearings are rated using an odd number between 1 and 9. The higher the number, the greater the manufactured precision of the bearing. Bearings manufactured within tighter tolerance ranges provide greater accuracy of shaft rotation and contribute to higher speed capability. However, the ABEC rating does not specify many other critical factors, such as smoothness of the rolling contact surfaces, ball precision, and material quality[1].
But yea keep em cleen and dry and lubricated and if they are really nice you should take them apart and cleen them one in a while.
Clean your bearings regularly and ofcourse properly because the dirt inside it can affect the speed of your penny board. It also depends on what terrain you're at, because when you're using wheels lower than 59mm and you are cruising around rough asphalt you better save money for a new wheels 60-65mm is the best i think and also look on other forums i cant tell everything you need there are more experienced skaters out there.
The speed of snowboarding depends on how long you snowboarded without stopping and how steep it is. You can go really fast and you can go really slow.
Physics determines the basis of motion, friction, speed and other factors that lead into snowboarding. This is the easy answer.
Snowboarding demonstrates speed, velocity, and acceleration. It can also demonstrate a positive or negative value for velocity and acceleration.
skiing, skating, snowboarding, speed skating,
Who cares !! Snowboarding is a waste of time
It will have increase in speed with increase in time
It will have increase in speed with increase in time
snowboarding, skiing, bobsledding, luge, ice skating, hockey, speed skating :)
accelerate means to increase speed.
You can install a razor booster from razorblade.com that will increase gaming speed. If you want to increase internet speed or download speed, that depends on your router.
Wrestling, Cross country, skateboarding, snowboarding, ice and speed skating, and gymnastics to name a few.
In that case, the speed will increase.
