A Day of Labwork

Physics D, F and Honors Physics all worked on their static and kinetic friction labs. Physics D and Honors Physics completed the lab and Physics D began their data collection/analysis and will complete it tomorrow. For Physics D and Honors Physics, we'll discuss the lab tomorrow and use it to help illustrate our in-depth discussion of friction (Physics D) and weight and the normal force (Honors Physics).

Intro Physics reviewed their work with Newton's Law of Universal Gravitation, then turned attention to weight and free-fall. We defined free-fall, discussed examples of motion that were and were not free-fall in nature, explained why all objects fall to earth with the same acceleration due to gravity and also the difference between mass and weight. Tomorrow, we'll get more into the arena of air resistance and dip our toes into 2-dimensional motion.
