Depends on how much energy is applied to it.
Actually, it depends on the potential energy of the slope on which it rides, combined with the weight of board and rider, and related to the drag of air resistance and the wheel bearings. Personally, I have reached in excess of 35 mph. This was in the mid seventies, so was more than a little suicidal--no helmet, no pads, on a busy road.
There are several forces involved while riding a skateboard. The force of friction (air resistance and contact with ground) acting against the motion and the pushing force from when you push off with your foot acting with motion. There are also several normal reaction forces, the weight of the person on the skateboard and the weight of the skateboard on the ground.
No, because the orbital is really just an abraction - the electron isn't racing around the orbital like a racecar, so there isn't a speed. The orbital is a better measure of the electrons potential energy.
In physics, the kinetic energy of an object is the energy that the object possess, due to the fact that the object is moving. When the object/skateboard isn't moving it has no kinetic energy. However when it is given energy such as a push, it would move and keep going until it is stopped by another force, such as a wall.
speed is force because its using energy to move and it is movement because speed is work.
No. No object can move faster then light. However, Minato Namikaze (the Fourth Hokage) and Uchiha Madara posses the ability to move at speed nearing the speed or light, or the speed of light itself, utilizing the space-time ninjutsu.

grind
The wheels allow them to move. If you look at a skateboard it has wheels.
a grind
the easiest way would be to first immobilize the skateboard then, give the dog a treat for just being ontop of it, then as it becomes accustomed to that then slowly allow it to move, from there just slowly increase the speed and continue with treat eventually the dog will asume the speed with the treats
Gravity, friction, or wind drag.
the friction between the wheels and the surface of the ground affect the speed of the skateboard. fo instance if you ride the skateboard on a smooth surface (with less friction) the skateboard will go faster.
Move to a shipping area
If you are reffering to the 'Christ Air', that would be Christian Hosoi.
Move to a shipping area
To sign "skateboard" in American Sign Language (ASL), you would move your dominant hand in a bouncing motion, as if riding a skateboard, underneath your non-dominant hand. This sign represents the action of skating on a board.
he will require the same force to move backward but in the opposite direction
