Anatomy of a Skateboard
deck: the flat standing surface of a skateboard, usually laminated maple.
grip tape: sandpaper affixed to the top of the deck with adhesive, used to increase the friction between the deck and the skaters feet.
nose: the front of the skateboard, from the front truck bolts to the end.
rail: the edge of the skateboard, also, plastic strips attached to the boards underside.
tail: the rear of the skateboard, from the back truck bolts to the end
wheels: usually made of polyurethane and sized between 39 and 66 millimeters in diameter; their hardness is measured by durometer, a number ranging from 0 to 100soft wheels have a durometer of about 85, hard wheels have a durometer of 97 or higher
wheelbase: the distance between the front and back wheels, measured between the two sets of innermost truck holes.
air: riding with all four
wheels off the ground; short for aerial
backside: when a trick or turn is executed with the skaters back facing the ramp or obstacle.
Caballerial: a 360-degree turn performed on a ramp while riding fakie (backwards), named after skater Steve Caballero
carve: to skate in a long, curving arc
fakie: skating backwardsthe skater is standing in his or her normal stance, but the board is moving backward (not to be confused with "switch stance")
frontside: when a trick or turn is executed with the front of the skaters body facing the ramp or obstacle
goofyfoot: riding with the right foot forward, the opposite of "regular foot"
grind: scraping one or both axles on a curb, railing, or other surface, such as:
crooked grind: grinding on only the front truck while sliding
50-50 grind: grinding on both trucks equally
50-50 grind by Diego Bucchieri (QuickTime)
nosegrind: grinding on only the front truck
5-0 grind: grinding on only the back truck
kickflip: a variation on the ollie in which the skater kicks the board into a spin before landing back on it

Kickflip by Tony Trujillo (QuickTime)
McTwist: a 540-degree turn performed on a ramp, named after Mike McGill
mongo-foot: a style of pushing where the back foot is kept on the board and pushing is done with the front foot
nollie: an ollie performed by tapping the nose of the board instead of the tail
Nollie by Matt Fields (QuickTime)
noseslide: sliding the underside of the nose end of a board on a ledge or lip
ollie: a jump performed by tapping the tail of the board on the ground; the basis of most skating tricks
railslide: a trick in which the skater slides the underside of the deck along an object, such as a curb or handrail
regular foot: riding with the left foot forward, the opposite of "goofyfoot"
shove-it: a trick performed by spinning the board 180 degrees beneath the feet while traveling forward
switch stance: riding the board with the opposite footing than usual, i.e., "goofyfoot" instead of "regular foot"
tailslide: sliding the underside of the tail end of a board on a ledge or lip
Types of Skateboarding
street skating: skating on streets, curbs, benches, handrails and other elements of urban and suburban landscapes.
vert skating: skating on ramps and other vertical structures specifically designed for skating.
Physics Glossarycentripetal force: a force that keeps a body moving in a circular path
rotational inertia: a measure of an objects resistance to being turned, depending on both the mass of the object and how that mass is distributed
work: force applied over a distancefor example, you do work when you push a box across the floor, but not when you push on a locked door; work done on an object or system results in an increase in the energy of that system
