Another Week Begins

Physics did a nice job listening to me gab on about Newton's 2nd and 3rd Laws of Motion and correlate the previous few days labwork with the theory in the text. Tomorrow, we expand the idea of forces and motion into the area of specific forces - weight, normal and friction. We'll keep things fairly unidimensional, but will look over some 2-dimensional examples in class.

Physical Science started examining their first field force - gravity. Be able to work with the formula for Newton's Law of Universal Gravitation (yes, it is on the MCAS formula sheet) and understand the theory that is expressed by the formula. The lab tomorrow will examine acceleration due to gravity - make sure you have read over the lab by class time. We will discuss the homework from today on Wednesday, along with the lab, and tie together the ideas of weight and gravitational forces. Be ready for another math packet dealing with gravitational forces to be tossed at you in the near future.

Honors Physics completed the static and kinetic friction lab today. Some groups had to re-evaluate data and collect a few additional data points for the coefficient of friction piece, but things look pretty good as of now. We will discuss the lab results tomorrow and begin a discussion of frictional forces, their impact on motion and the meaning of that pesky coefficent of friction.
