06 January 2016- Position | PWN Physics 365

On this day in physics: 06 January 1745, 1745 Birth of Jacques-Étienne Montgolfier, co-inventor of the hot air balloon along with his brother Joseph-Michel (Source).

Word of the day: Position- Position is where something is with respect to a given reference point, or coordinate axis. For example, on earth, we are able to describe accurately any position on the face of the planet with specific latitude and longitude coordinates. In physics, usually the position of objects is described with respect to a coordinate axis. In 2 dimensions, which represent the flat ground, like a parking lot, we can say a car which is about to drive is currently at rest, at position (5,0). This means that if you know where our reference point is, (0,0), without even seeing the car you can predict where it is. Position, and the change of position, is analyzed in a study of motion referred to as kinematics.

In mathematics, the position is generally denoted x(t), or y(t), depending on which direction the object is moving. The (t) is to denote that the position will change as time moves on, as most objects do.
