Figure 3.8: Motion diagram and free-body diagram for a box being dragged to the right, by means of a string, across a flat surface. Step 4 - Compare and contrast the free-body diagrams you drew in steps 2 and 3. The free-body diagrams are quite different, with one having no forces and the other having four.
force is an interaction between two bodies or between a body and its environment. One intuitive type of force is a contact force, which often clearly involves a direct interaction (or contact) between the surfaces or boundaries of the bodies involved. We can further discriminate between different kinds of contact forces.
Example: Components of the force vector F~ 1.1 Superposition of Forces When two or more forces F~ 1, F~ 2, etc., act at the same time on the same point of a body, experiments show that the motion resulting from these multiple forces can be produced by a single force R~, the vector sum of the original forces: 1
Remember to add the forces as vectors. The resultant force on q 1 is the vector sum of all the forces exerted on it by other charges. For example, if four charges are present, the resultant force on one of these equals the vector sum of the forces exerted on it by each of the other charges. F F F F 1 21 31 41 Section 23.3
example forces exerted by a damper or dashpot, an inerter, and interatomic forces are discussed in Section 2.1.7. 2.1.1 Definition of a force Engineering design calculations nearly always use classical (Newtonian) mechanics. In classical mechanics, the concept of a `force’ is based on experimental observations that everything in the universe

Lecture 7: Newton’s Laws and Their Applications 1. Chapter 4: Newton’s Second Law F~= m~a First Law: The Law of Inertia An object at rest will remain at rest unless, until acted upon by an external force. An object moving at constant velocity will continue to move at constant velocity unless, until acted upon by an external force.
