A force is a push or a pull that acts upon an object. Object A in this case is an innovation or change idea related to fire protection, as a result of its interaction with another object, object B in this case the fire protection industry. Forces result from these interactions! We will discuss some these forces and how the result from contact interactions (normal, frictional, tensional, and applied forces are examples of contact forces) and other forces that are the result of action-at-a-distance interactions. According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. Object A exerts a change force, and Object B exerts a resistant force. These two forces are called action and reaction forces and are the subject of Newton’s third law of motion. Formally stated, Newton’s third law is:
For every action, there is an equal and opposite reaction!!!!
