Define specific terms: equilibrium, force, net force, tension, vector
Use examples to demonstrate how the combination of all forces acting on an object will result in a vectored net force. Demonstrate using a kg mass with 2 spring balances to arrive at a zero net force. Demonstrate how the stretching of a spring in a spring balance translates into a "stretching force" which is tension. Draw and explain the use of force vectors to demonstrate a vector quantity with magnitude and direction. Differentiate between a vector quantity and a scalar quantity.
Discuss the use of mass spectrometry in determining the average atomic mass of an element based on the abundance and mass/charge of all the isotopes. Identify elements and mass using the spectrum of an element. Identify 3-4 elements listed using this method. Examine a sketch of how the spectroscope works.
We discussed prerequisites for calculus. We reviewed the concept of a limit in calculus by doing examples emphasizing the notation and definition of a limit.

The definition of limit is a difficult concept. Finding limits is not difficult, but justifying the value using the definition takes time to grasp completely. We will work more on this concept next week,
Continue reading Silas Mariner chapter 2. Complete the questions found in the packet as he reads. Ask questions about the content that he has read so far and give any opinions he has formed to this point in the story.
List and discus the Common SI units used in physics, along with a few of the derived units.
Discuss mechanical equilibrium. Define and explain a force. Discuss resting motion and non resting motion. Indicate why a force is needed to change the state of motion. Examine examples determining the net force exerted on an object. Define tension, weight, and stretching force
Given the molecular formula of acethylsalicyli acid Determine the mass in grams of a given sample, define mass in terms of molar mass x number of moles. Determine the Molar mass from the formula and calculate the mass in grams from the sample. Calculate number of moles contained in 1 g of ASA if the % is 75.2%. Analyze the structural formula as drawn
Determination of %^ of an element in a compound.based on mass during a reaction. Determine the atomic weight of iron based on experimental yields of iron oxide produced during a reaction.
Discuss how math describes ideas which are unambiguous in physics. Use Ohms law to explain how concepts of electricity in a circuit can be determined by a math formula, which remains constant. Use examples of V = I x R and discuss how each answer depends on the formula.
