Machine Dynamics, Machining, and Mechanical Systems
Machine Dynamics and Mechanical Systems
A machine is a physical system that uses energy to apply forces and control movement to perform an action. Dynamics is the part of physics that studies the motion of objects and their response to the forces acting on them. It relates the concepts of force, mass, and acceleration. The principles of dynamics are Newton’s laws:
- First Law of Newton: Principle of Inertia
- Second Law of Newton: Principle of Force
- Third Law of Newton: Principle of Action and Reaction

Forms of Social Grouping: Group, Society, State
Another important way to study the relationships between the individual and society refers to forms of social grouping. The individual is the smallest unit, the building block of society.
A social group is the set of people who interrelate with one another because they share the same rules, values, and purposes. They share a common identity.

- Secondary groups:

Post-WWII Economic Shifts: Recovery, Golden Age, and Global Impacts

The first economic aid to Europe came mostly from the U.S. and had two sources:
