In this module the forces (elements Force or Friction) are added to the objects (elements Mobile and Spring) placing the force in one of the cell around the object. Each object (if there isn’t in the chalkboard’s border) have 8 cells around it. This module have 42 elements described below, its data, equations, and what elements and combinations allows.

In this module the elements Object in rest, Mobile with linear movement, Mobile with circular movement, Mobile with polar circular movement, Spring and Center of rotation are used to set the initial and final state, separately, of the problem. Then both states are related through the elements Energy, Angular Momentum, Linear Momentum and/or Power. The element Mobile with perpendicular circular movement can be used to set/know additional conditions (see examples).

Note: Items Energy, Angular Momentum, Linear Momentum and Power, admit only certain combinations of objects. And although in general the user should not worry about this, at the end of this section we provides as reference a complete list of supported combinations for each of these elements.
