This book presents Motion, Momentum, Speed, and Friction in completely new ways. Forget what you have read in traditional physics texts, this book provides the more accurate (and more intuitive) explanations. There will be no mathematics. Instead, we will be looking at physical entities (such as molecules and energy strings) as they perform their real world activities. Furthermore, there are many new concepts here. This book is part of the New Physics, where I bring physical science to a completely new level of understanding. In particular, major new concepts presented include: the cause of motion for objects, the meaning of momentum, the physical entity of friction, and a more precise understanding of the speed of light. Topics discussed in this book include: The Process of Motion understood using Atoms and Energy Strings Momentum explained through Atoms and Energy Strings Self-Propelled Objects Energy versus Speed Energy Transfer Processes Stationary, Faster, and Slower Objects Sudden Stops and Turns - with Results on Passengers Energy Flows in Multiple Directions Observable Motion and Observable Momentum Friction Understood as Physical Entity Coefficient of Friction explained Physical Entities Friction and Momentum in the Same Situation Speed of Light: Constant Energy versus Constant Speed After reading this book you will understand motion, momentum, and friction much more accurately. You will be able to apply these concepts, intuitively, to any situation involving motion."
