TOPIC  READING  PROBLEMS  EQUATIONS/RELATIONS/CONCEPTS  
The Importance & Some Important Vectors & Scalars Displacement & Velocity Average Speed 
For all subsequent lectures, Any Reading, Is Due on the Date * * * Introductory Reading 
No Problems Due for First Class 
IN BRIEF & INEXACTLY: Distance: how far? Displacement: how far & what direction? Speed: how fast? >Velocity: how fast & what direction? 


Skim: Read: 
Due: As you work on these assignments, please keep in mind the explanations of distance, displacement, speed, & velocity provided in the box diagonally upright from this one. (Distance = "how far?", etc.) When answering a question that asks for a vector quantity (e.g. velocity, displacement), try, if possible, to give a direction in words.
Do NOT overlook the HW GUIDES linked in the Feb 22nd assignment box!! 
Can you translate each of the above equations into words? Into a complete and coherent statement about motion...

HOW TO STUDY
Looking for more practice? Try this exercise. Practice Many Problems

Galileo's Principle of Relativity Form #1: The laws of physics hold in all unaccelerated reference frames*. Form #2: No experiment can measure the velocity (speed & direction) of a solitary object; the velocity of an object cannot be measured in comparison to space itself. Form #3: Velocity (speed + direction) is a relation, not a property; the motion of one object is not meaningful without comparison to another object. *A reference frame is a perspective. More precisely,
a reference frame is a coordinate system defined in relation to an observer that
moves with the motion of the observer.

Galileo's Principle of Relativity, Form #5 Commonly knwn as Unless acted on by a net external force, an object at rest stays at rest and an object in motion stays in motion at the same speed and in the same direction.

Newton's Third Law of Motion If object A exerts a force on object B, then object B exerts a force on object A of equal magnitude and opposite direction.
