Concept Questions
... Answer 3. Energy is not conserved because there are energy losses due to kinetic friction. Angular momentum about the center of mass is not constant because the friction exerts a torque about the center of mass. Angular momentum about a fixed point on the ground is constant because the sum of the to ...

Chapter 1 THE NATURE OF PHYSICS
... According to one of definitions, physics is the study of matter and motion. Neither this nor any other sentence definition can adequately reflect the mixture of created error, accumulated knowledge, unifying ideas, mathematical equations, philosophical impact, and practical application that comprise ...

Characteristics of Force
... "If a body is accelerating, then there is a force on it." That is what Newton's laws say, so the most precise and beautiful definition of force imaginable might simply be to say that force is the mass of an object times the acceleration. Suppose we have a law which says that the conservation of mome ...
