Image Being Shown Is A Skateboard

The board should lay flat on the water with the rider’s heels on top of the board.

wheels that runs underneath the track. This keeps the cars from flying up into the air.

Skateboarding has been around since 1944. Initially, created as a crate with wheels and a bar used as a handle bar, the idea was slowly being more refined. Woman’s Army Corps Betty Magnuson, reported seeing French children riding on wooden boards with rollerblade wheels attached to them which would imply that the idea has been played around with but never capitalized upon. From crate boxes with handle bars, to popsicle shaped boards with specialty made wheels backed with a massive culture, skateboarding has become a popular industry.

Once accomplishing the motion of your hips, a player must focus on the next link in the chain, pulling the stick away from his body, preparing to move forward (accelerate) with a shot. A goalie uses his or her angle of perception to watch the ball and to make a save. The intent is to hide the head of the stick behind the player’s body to decrease the visibility of the ball to the goalie. The more a shooter hides the head of the stick the less likely the goalie with stop the ball from accelerating into the back of the net. When the act of pulling the stick takes place, a shift in weight occurs. “This shift in balance enables the player to release the ball while allowing his hips and back to recoil and urge the shoot motion in a forward direction. This forward acceleration causes an increase in the player’s velocity, zero to forward” (Russo, 1). Depending on the magnitude of your acceleration depends on how “hard or fast” the player pushes off the ground with their foot allowing them to make the initial forward progress. Without the push off the ground, no forward movement would be possible.

The fastest growing sport in America is lacrosse, and in order to play lacrosse, it is important to first understand the physics of the game. Lacrosse players around the world use physics while playing without even thinking about it. With no knowledge of physics, it would be pretty difficult to master the fastest game on two feet. One of the worlds greatest scientist, Isaac Newton, established three laws dealing with physics, and using these laws will make it possible for a lacrosse player to understand what he or she needs to do in order to throw a ball. Newtons first law deals with inertia, his second law deals with the relationship between mass, acceleration and force, and his third law deals with opposite reactions. When talking about lacrosse, it is essential to cover Newton’s first law, his second law, and his third law in order to understand the physics behind throwing a lacrosse ball. .

Bonnechere et al. supports their claims by conducting a biomechanical analysis on twenty five males, all young and fit, and recording measurements in different areas (Bonnechere et al., 2014). However, the study exemplified field-of-view (FOV) and kinetic energy, and their relation to sprint starting positions and safety. Field-of-view is “[a] ratio between the height of the head and Verticality [,]” (Bonnechere et al., 2014). An increase in FOV will lower the injury risk, because players are more alert of their environment. Ergo, they can avoid injury. According to the averages of each stance and the categories, initial position and motion, “[t]he FOV is increased when adopting a 2-point starting position because the trunk is more vertical,” (Bonnechere et al., 2014). Simply, when the angle between the body’s trunk and head is approximately straight, the FOV is high.

With the evolution of skateparks and ramp skating, the skateboard began to change. Early skate tricks had consisted mainly of two-dimensional maneuvers like riding on only two wheels ("wheelie" or "manual"), spinning only on the back wheels (a "pivot"), high jumping over a bar and landing on the board again, also known as a "hippie jump", long jumping from one board to another (often over small barrels or fearless teenagers) or slalom. The flat ground ollie allowed skateboarders to perform tricks in mid-air without any more equipment than the skateboard itself, it has

B. To skate on RollerBlades takes a lot of effort. First thing you have to do is to maintain balance on the skates. Find a solid wall or something else to hang on to. Bend your knees and hold on to the wall, then hold up one leg. When you can do this properly, let go of the wall and try it without hanging to the wall. When you complete that you need to learn how to start rolling. When you wan to roll you need to make your legs a 90 degrees angle than push with the

Newton’s First Law of Motion, inertia, says that an object at rest will remain at rest and an object in motion will remain in motion will remain in motion unless acted upon by an unbalanced force. The ball will not move forward until the server hits it into play and it will not stop until it hits the net or the ground. The second part of the law is momentum where an object in motion will stay in the motion of a straight line with a constant speed unless acted upon by an unbalanced force. The ball will continue to move in a straight line or an arc until a player blocks the ball from traveling any farther. Newton’s Second Law, force, states that force equals mass times acceleration (F=ma). For volleyball, the more force applied to the ball, the further it will go. This is very important in volleyball because the players need to have the perfect amount of force on the ball to get it over the net but keeping it in bounds. Newton’s Third Law of Motion states that for every action there is an equal and opposite reaction. The player hits the ball with a certain amount of force, the ball hits the player’s hand with the same amount of force. In volleyball, the player’s upward motion pushes the ball up, where the opposite reaction is the downward motion of the player’s arm after hitting the ball

5. A hockey player hits a puck at one end of an empty skating rink. The puck travels across the ice in a straight line until it is stopped by the goal at the other end. Explain how each of Newton’s laws of motion applies to this situation.

Peralta shows several members of the Z-Boys explain through expert interviews, the arduous task of creating skateboards, as commercial skateboards were hard to find. Their skateboards used clay wheels, which would “lock up” and injure the rider if they turned too hard or hit a pebble on the road. This did not have any real negative effects on the Z-Boys and they continued to use this particular design until the invention of urethane wheels. Another example of the Z-Boys ingenuity is their incorporation of surfing into skateboarding. The Z-Boys all came from surfing backgrounds and incorporated these styles into their skateboarding. This emulation of “surfing on asphalt waves” would continue to used as the basic skateboarding style of the

Plies – For beginners, Plies are the wood layers used to produce the skateboard deck. These plies play important role in sustaining pressure and making sure the board stays intact without breaking. A standard board consists of 7 or more layers of compressed wood which gives the compactness to the deck. During the selection of a brand make sure to ask about the plies as durability is highly dependent on it.
