Hi

Maybe the dynamics of “n” (1, 2, 3, …) bodies can be made more comprehensible if we place equations in a table. This way, we can make explicit the following aspects:

- we have to apply Newton’s equation “2n” times; twice per body: once in the normal axis and again in the axis of motion
- each axis has its own properties: (1) in the normal axis the bodies have not acceleration and, as a consequence the sum of forces upwards are equal to the sum of forces downwards and (2) the forces in the direction of motion are positive and the forces against the direction of motion are negative
