12. Emir Vela Space : is the environment in which objects move; a collection of location or points. Time : is a scalar variable to allow us to specify the order of a sequence of events. Force : interaction between and object and its environment. Magnitude, direction, and sense. Mass : measure of the amount of matter in the object. Fundamental Concepts

13. Emir Vela Inertia : body’s resistance to changing its state of motion in response to the application of a force system. Depends on mass and geometry of the body. Particle : is an object whose mass is concentrated at a point. Considered to have ZERO volume. Rigid Body : is and object whose mass is distributed over a region of space. The distance between any 2 points in the object never changes. Fundamental Concepts
