Describe acceleration in terms of velocity change and time and how rapidly velocity changes. Examine unbalanced forces, equilibrium, constant velocity, and acceleration. Determine how acceleration is directly proportional to the net force. Based on a graph, show how acceleration is inversely proportional to the mass. State Newton's 1st law both in written terms and by formula.
Solve problems using all 3 arrangements of the law.

Discuss friction as a force. Example how friction occurs between two surfaces due to microscopic variations in the surface, like microscopic bumps. Discuss and explain static and dynamic equilibrium. Discuss how equilibrium can exist for a moving object as well as a stationary object. The sum of the forces on an object at equilibrium equal zero. Demo using a cup, card and coin.

Use demo materials to elicit the formula relating pressure, force and area. P=F/ A. Determine that Newtons/meters square are referred to as Pascals. Discuss friction as a force, include air resistance as friction. Define free force. Discuss the acceleration due to free fall, label it g and define it as the force/mass. Elicit how g is the same regardless of the mass used in free fall.

Discuss why and how the combination of all forces acting on an object become the net force.
Determine the net force on a block of wood under different force measurements. Determine the net force being zero when the vector quantities are in opposite directions. Discuss tension as a force. Indicate tension as a stretching force. Determine how a mass and tension can equal zero. Introduce force vectors to magnitude and direction. Discuss friction, support force and normal force. Introduce static and dynamic equilibrium.

Demo how force and pressure are related to how we feel a mass. Elicit how the pressure will change on a force when the area the force acts upon changes. Determine that for a constant force increases in the area of contact results in a decrease in pressure. Determine that the pressure is directly related to the force and inversely related to the area. Derive the formula pressure=force/area. If force is in Newtons and area in square meters, then pressure is in Pascals.

Introduce SI units applicable for physics. These would include the names and shorthand for length, mass, time, temperature and force. Define equilibrium in terms of harmony and balance. Demo wood blocks in equilibrium and then how we can change the equilibrium by applying force. Define force and define states of equilibrium.

Discuss early views of physics as natural philosophy proposed by Aristotle. Discuss reactions to some laws proposed, which though wrong, had been believed for centuries. Use example in which Aristotle proposed, and most people believed, that a heavy object will fall at a faster rate of speed than a lighter object made of the same material. Introduce why physics is the study of the physical world dealing with matter, force, energy, motion, heat and light, and atomic structure. Discuss how the language of physics is unambiguous with no double meanings. Use as example the relationship between voltage, current and resistance when discussing electricity.

Prepare and analyze a graph using the results from last Friday's lab dealing with acceleration due to changing force.
Discuss friction, outline parameters which describe friction. Concentrate on friction being a force. Discuss constant velocity when friction and force are equal. Introduce force and pressure relationship. Elicit why and how pressure difference is due to force/umt area

Use diagram of a typical nuclear reactor. Discuss the function of the major sections used to produce electricity from nuclear fission. Discuss the fuel rods and the need to control the fission. Discuss waste removal problems. Diagram a typical fusion reaction and the conversion of hydrogen nuclei into helium nuclei, with a tremendous release of energy. Discuss the thermal requirements for the reaction to occur, and why cold fusion is being explored.

Investigate the effect of changing mass on acceleration. This was the lab prepared for Thursday. The lab was shortened slightly to fit into the one period time slot, Thursday's time would have been 2 periods.
