27.5 Putting Vectors to Work: Geometry and Physics
Point 5 of 7
27.5.5 The Vector Model for Forces
Core idea
When several forces act at one point, add them with the parallelogram rule to find the resultant, which is zero when everything is in balance.
Module goal. Use vectors as a toolkit to prove geometric theorems, compute lengths and angles, handle forces and velocities, and lay the groundwork for vectors in space.
