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.
bECAUSE IT HAS WEELS
it depends on how steep the slope is.
depending on your bearings
No know this because they have this sticky slim that makes them go slow they would have to have to have legs to go fast
well that depends. a skateboard goes pretty slow on rough terrain unless you have soft wheels. rollerblades are a bit more all-terrain but you can also get all-terrain wheels for a skateboard, too. skateboard just FLIES going downhill. you go really fast.
not a fast but slow
slow-fast-slow (Apex)
fast and slow
slow

YES!! slow songs makes your heart rate slow down and fast songs make it speed up.
