Laws of Nature 1. Gravity: Gravity is the natural force that constantly pulls all things to the earth and affects an object’s weight. Center of Gravity is a point where the mass of the vehicle is concentrated and balanced. The higher the center of gravity, the more unstable the vehicle becomes. When a driver brakes, accelerates, or corners, the G forces are amplified. 2. Kinetic Energy: Kinetic energy is the energy an object possesses due to its speed, or velocity (v) and its mass (m) : KE = 0.5 ∙ m ∙ v2 The faster the object moves, the more energy it collects. A heavier moving object will have more kinetic energy than a lighter object moving at the same speed. A vehicle’s kinetic energy can be overcome by brakes, friction, air resistance and gravity. 3. Momentum: Momentum refers to the quantity of motion an object has, measured in kg ∙ m/s Formula: p = m ∙ v. The more mass and more velocity an object has, the more momentum Change in momentum is called impulse; the magnitude of impulse is based on the amount of opposing force and the time span over which that force is applied. 4. Inertia: an object’s tendency to resist any change in its state of motion. 
5. When driving through a curve, inertia creates the sensation that you are being pulled toward the outside of the curve. Why does this happen? Because you are traveling in a straight line, and inertia wants to keep you going in a straight line

Vision and Driving 1. How do you think your vision impacts your driving? 2. Visual Perception: The eyeball’s ability to distinguish the number, shape, and color of an object. Perception 3. Some key points on drivers and decision-making: Drivers make decisions based on about 90% on what they see Drivers make decisions based on about 10% of all on what they hear or feel Directory: cms -> lib4 -> VA01000195 -> Centricity -> Domain Domain -> Pages 816-820 Truman’s domestic policies after the war—Truman was tasked with reconversion to a peacetime economy and introducing his domestic agenda Domain -> Pioneers of Sports & Entertainment Industries Matching Exercise Domain -> Unit 3: Introduction to Sports & Entertainment Business Principles Domain -> Apush period two key concepts review (1607-1754) This review refers to some examples we did not go over in class – so don’t stress about those!
