Question

Why is it important to clearly define the coordinate system you want to use when analyzing objects in free fall

Answer 1

Answer:

Understanding projections and coordinate systems important knowledge to have, especially if you deal with many different sets of data that come from different sources. Projections Distortion Coordinate Systems Datums

A Cartesian coordinate system. Locations on the Earth's surface are measured and represented in terms of coordinates; a coordinate is a set of two or more numbers that specifies the position of a point, line, or other geometric figure in relation to some reference system.

• Check Layer Properties > Source > Spatial Reference to find out what coordinate system your data is in. If it says “Unknown Coordinate System” you definitely want to use the Define Projection tool. • The Define Projection tool will not make a copy of your data.

Math coordinates identify the location of a point on a graph or map. The ordered pair, (x,y) is the address of the point. The Cartesian coordinate system is the graph used to locate the point.
