"Regardless of what may you have been told or assumed, physics is not intrinsically a hard subject.  Instead, people find it difficult because it requires a detail-oriented, organized thought process.  Success, then, is more about learning to think appropriately and less about memorizing equations and example solutions.  Once you've mastered how to think about solving physics problems, it doesn't matter what problem is thrown your way--you will be able to solve it."
     --Teman H. Cooke, First Semester Physics Survival Guide: A Lifeline for 
       the Reluctant Physics Student, Three Friendships Company (2013), p. 3.

     (In the ideal case that there is no external impulse on a system of two colliding objects, then momentum is "conserved" and can be transferred between these two objects without loss.  However, kinetic energy can either be conserved or lost depending on the amount of deformation involved in a collision (even though momentum is still conserved); these are classified as elastic, partially inelastic, or completely inelastic.)
