Speed

In everyday use and in kinematics, the speed of an object is the magnitude of its velocity (the rate of change of its position); it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero.

Like velocity, speed has the dimensions of a length divided by a time; the SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the US and the UK, miles per hour. For air and marine travel the knot is commonly used.

The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in a vacuum c = 7008299792458000000♠299792458 metres per second (approximately 7008299722222222222♠1079000000 km/h or 7008299963840000000♠671000000 mph). Matter cannot quite reach the speed of light, as this would require an infinite amount of energy. In relativity physics, the concept of rapidity replaces the classical idea of speed.

Skate 3

Skate 3 is the third installment in the Skate series of video games, developed by EA Black Box, and published by Electronic Arts. Released on May 11, 2010, It is the sequel to the 2009 game Skate 2.

Plot

Some time after Skate 2, the skater has proven that he's one of the best, and now goes by the alias "The Legend". Now he's attending the Port Carverton University. He was just stunned how the city is the "polar opposite" over San Vanellona. After a failed attempt to "Jump The Shark", a Thrasher challenge at the stadium, his next goal in life is to be the best skating mogul. By making a team composed of skaters like him, his goal is selling over a million boards while doing the same odd jobs around Port Carverton.

Gameplay

The game takes place in the fictional city of Port Carverton, which embraces skateboarding, unlike the "skateboarding is a crime" mentality portrayed in the second game. Although the location is a more colorful and friendlier place than Skate 2's desaturated, and grainy streets, the gameplay provides a similar feel to the first and second games. Port Carverton is made up of three districts, Downtown, the University, and Industrial. Although the overall look of the city is very clean (except industrial) each district has its own unique designs and monuments. Downtown is full of slick rigid ledges and rails, while the University is full of banks and open areas. Industrial is the most unique; it is home to a huge quarry that has bricks of stone.
