Now days skateboarding is one of the most practiced sports in the world.

There are people trying to prevent you from skating anywhere. This is truly an injustice to skaters everywhere. Here in our country is not different from everywhear we get kick out from everywhere, there's a small number of places to skate one of the is our new skate park located in the Olympic Center.

This are the things that people use to stop skaters from skating handrails.



Many people consider skateboarding wrong, don't know why its just a regular sport. People always that we could get hurt by doing the things we do, but why do they care, in my opinion that's our responsibility what we do for fun.


roller-skate wheels, the sidewalk surfers of the 30s, 40s, and 50s had a straightforward mission: Start at the top of a hill and ride down. The primary goal was just to stay on and avoid collisions; given the humble equipment and rough road conditions, it was no small challenge. Now, thanks in part to improvements in design and materials, skateboarders have a higher calling.

In a blur of flying acrobatics, skaters leap and skid over and onto obstacles, executing flips and turns of ever increasing complexity--all at top speeds. For onlookers and beginners, it can be hard to follow the action, let alone answer the question that springs naturally to mind: How on earth do they do that? While it may seem that modern skateboarders are defying the laws of physics, the truth is that they're just using them to their advantage. Let's take a closer look at some fundamental skateboarding moves and the physics principles behind them.



Jumping the ollie

Invented in the late 1970s by Alan "Ollie" Gelfand, the ollie has become a skateboarding fundamental, the basis for many other more complicated tricks.
In its simplest form, the ollie is a jumping technique that allows skaters to hop over obstacles and onto curbs, etc. What's so amazing about the ollie is the way the skateboard seems to stick to the skater's feet in midair. Seeing pictures of skaters performing soaring 4-foot ollies, many people assume that the board is somehow attached to the skater's feet. It's not. What's even more amazing about the ollie is that to get the skateboard to jump up, the skater pushes down on the board! The secret to this paradoxical maneuver is rotation around multiple axes. Let's take a closer look.



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 skater's 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 board's underside.

tail: the rear of the skateboard, from the back truck bolts to the end

trucks: the front and rear axle assemblies that connect the wheels to the deck and provide the turning capabilities for the board.

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 100—soft 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.


Skateboard tricks

air: riding with all four wheels off the ground; short for aerial

backside: when a trick or turn is executed with the skater's 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 backwards—the 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 skater's 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

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

McTwist: a 540-degree turn performed on a ramp, named after Mike McGill

: 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

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

: 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

Tipes 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.

half pipe: a U-shaped ramp of any size, usually with a flat section in the middle

vert ramp: a half-pipe, usually at least 8 feet tall, with steep sides that are perfectly vertical near the top.

Phisics Glosarie

centripetal force: a force that keeps a body moving in a circular path

rotational inertia: a measure of an object's resistance to being turned, depending on both the mass of the object and how that mass is distributed

work: force applied over a distance—for 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
