Hi all,

This post will be exceptionally crucial when doing sports as this encompasses all forms of physics principles viewing sports. By following them, you will be ensured to win the first in a race.

1. There is no use running fast. Since you are running around the track, there is ZERO displacement in 400m running events. Therefore, you achieve 0 velocity and thus 0 speed.

2. When running 100m, 200m running events, remember to state if you are measuring absolute speed or relative velocity. Please note that absolute velocity will be approximately 130km/s as the Earth is moving across the Milky Way. Relative Speed will be the speed you achieve by running.

3. Do remember to ask the person timing you to account for time dilation which is about 10^-13 seconds for running for 10 seconds at world record speed of 10m/s. Corralis forces must also be accounted.

4. Time standard must be clearly defined as anyone can define one second as an oscillation made by a pendulum in space (zero-gravity). Parallax error must also be accounted as gravity of the watch and electrons involved in time-keeping bends light to a certain extend, though not observable.

5. The faster you go, the less accurate you will be able to define your position. Therefore, don't run too fast or else the time-keeper will not be able to take down your timing due to infinite uncertainty in your position.

6. Make sure you are distant from any massive objects, such as concrete slabs should ever they bend light and cause the reflected rays from you not reaching the spectators and the time-keeper.

Be sure to take all neccesary physical precaution and good luck for the upcoming sports day!

Regards,
Bryce
