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...

IMPORTANT ANNOUNCEMENT: The Bird Man problem has been CUT from the practice exam. Practice Many Problems
System Schema & FreeBody Diagrams

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.

System Schema & FreeBody Diagrams

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 Second Law of Motion: >

Problem III.A, in NII.1, is designed to help you figure out how to calculate the force of gravity on an object, given its mass. If you get stuck on this, the answer is in the textbook reading . EXTRA CREDIT:

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.
