Study route
11.1. Movement and reporting system
The position is given by coordinates and the displacement by vector from the initial point to the final point.
11.2. Equal speed
The velocity changes linearly over time and the coordinates over square law.
11.3 Free drop
- Near the surface of the Earth, all bodies without air resistance fall at the same acceleration g. Vertical traffic is a private case of equiacceleration.
