Variable mass

| C |
in the palette on the schematic
The block is designed to simulate the translatory motion of a body having a variable mass. The block calculates the linear acceleration of the body and determines the speed and position of the body using integration. Linear acceleration a in m/s2 is calculated by the formula:

where:
  • N – number of blocks connected to this block
  • Fi – force coming from the i-th block, N
  • M – defined body mass, kg
  • Mmin – minimum body mass, kg
