Physics Post 6

For this physics post I will be explaining this picture I took of a vector on my bed. Since there are no defined axes, a person would not know which direction or the scale of this vector. Without the axes or any other type of line to show direction, a person could not define what direction this arrow is going therefore, by definition, making this not a vector since there is no direction. As an example, a scale that you could use in this picture would be the squares on my bed. If a person took the two tan lines closest to the tail of the arrow and used those as the x and y axis, and estimated that each square was about 3 centimeters, they would find that the arrow is about 22.5 centimeters. Assuming that 1 centimeter is equal to 1 meter per second, this arrow has a magnitude of 22.5 meters per second. Also considering that the edge of my bed that is showing is facing north, then a person could guess this arrow is facing southeast, giving the vector a direction.
