Relationship between Speed, Distance and TimeSpeed is a measure of how fast an object travels a certain distance, or how far an object travels per unit of time.
The speed of an object is calculated by the following method: Speed = Total Distance travelled/Time taken to travel that distance. The greater the speed, the further the object travels in a set period of time and the time that is takes an object to travel a set distance is shorter. The speed of an object usually changes throughout it's trip, so this formula is used to find the average speed of an object. We can rearrange the equation above to find the Distance and Time travelled by an object: Distance = Speed x Time Time = Distance/Speed The speed triangle (on the left), helps to remember this relationship. |

For accuracy and reliability, the speed is recorded using many pieces of technologically advanced timing equipment such as photoelectric cell (laser beam) and composite imaging. To ensure the sound of the 'gun' to signify the commencement of a race is heard at the exact same time by every athlete (even if it would differ by a millisecond to a closer competitor), the sound of the gun is loudly played throughout speakers, equally distanced from each athlete. Factors that could affect a swimmer's speed in an Olympic race include: -Turbulence: the waves created by swimmers, that swimmers behind get slowed down by. Direct Turbulence is waves created from swimmer to swimmer. Reflected Turbulence is waves pushed from walls to athletes. -Pool Depth: similar to Turbulence, the depth of the pool can cause waves from the pool's bottom to the athletes swimming on the surface, affecting their performance. The Standard pool depth are seen in the image on the left. -Water Temperature: waters set at FINA competitions are set between 25 and 28˚C. Water temperatures too hot can cause the athletes to overheat and lose energy and too cold temperatures could cause the swimmers to not be able to function their muscles properly or shock them. |
