What Do Forces Do? Video Tutorial

The What Do Forces Do? (Balanced vs. Unbalanced Forces) Video Tutorial explains the effect of forces upon the motion of objects. The role of balanced and unbalanced forces is discussed. The various representations - force diagrams, dot diagrams, p-t graphs, and v-t graphs for stationary, constant speed, speeding up, and slowing down motions are associated with each other. The video lesson answers the following questions:

  1. In what way do forces affect the motion of an object?
  2. ​What do the force diagrams look like for speeding up and for slowing down objects?
