Objectives.
[1] Be able to convert back and forth between inches, feet, meters, and miles.
[2] Understand the meaning of the metric prefixes mega-, kilo-, centi-, milli-, and micro-.
[3] Know what is meant by the term "Uniform Motion".
[4] Know what is meant by the expressions Dt and Dx, and be able to calculate them given xi , xf , ti , and tf .
[5] Understand the definition of average speed. Given sufficient information, be able to determine the average speed of an object.
[6] Understand the definition of average acceleration. Given sufficient information, be able to determine the average acceleration of an object.
[7] Be able to interpret graphs of position vs. time, speed vs. time, and acceleration vs. time for an object. Be able to determine the kind of motion that an object is exhibiting by looking at one of these graphs.
[8] Understand what is meant by the term "Instantaneous Speed".
[9] Know the difference between "Position" and "Displacement".
[10] Understand the difference between "Time" and "Duration".
[11] For a ball that is released and allowed to roll down an inclined plane, know how the speed with which it rolls on the horizontal track at the bottom of the hill depends upon the release height.
[12] When either the position or the speed of an object is plotted as a function of time, understand the relevance of the slope of the resulting curve.
[13] Given numerical data about the motion of an object, be able to construct a graph representing its motion.
[14] Understand that objects falling freely do so with a constant acceleration. Know the approximate value of this acceleration near the surface of the Earth.
[15] Be able to use the constant value of acceleration near the surface of Earth to relate speeds, distances fallen, and times for objects in free fall.
[16] Be able to compare and contrast the ideas of Galileo and Aristotle as they pertain to freely falling objects.
[17] Understand what a vector is, and be able to combine vectors when they point in the same direction, point opposite to each other, or point at right angles to one another.
[18] Understand Newton's Three Laws, and understand that the First and Third are just special cases of the Second. Be able to use Newton's Laws to complete simple calculations.
[19] Understand the difference between mass and weight, and be able to determine one from the other, given sufficient information.
[20] Know what a free-body diagram is, and be able to construct one for a given object in a given situation if asked.
[21] Understand what sliding friction is, and understand the difference between kinetic and static friction. Be able to explain the factors that the strength of the frictional force depends on.
[22] Understand how the resistance provided by fluids depends on the velocity at which an object travels through the fluid.
