A Full Week! Almost...

We have a half-day tomorrow due to parent-teacher conferences, but this is more instructional time in a week than we've had lately, so yeah!

Physics A and B worked on the idea of elastic collisions, building on yesterday's work with perfectly inelastic collisions. Elastic collisions conserve both momentum and kinetic energy and we worked some problems putting those ideas to use. Tomorrow we'll have some review time in preparation for Thursday's exam. Then it's on to circular motion.

Intro Physics spent time discussing yesterday's density investigation and used that to springboard into the concept of pressure variations with depth in a column of fluid. As we descend in a fluid, pressure increases and as we ascend, pressure decreases. We contrasted gauge and absolute pressure and ended the class by starting on some problem-solving practice with these ideas. We'll go over the homework at the start of class tomorrow before looking at buoyancy and buoyant forces.

Honors Physics worked on an activity to demonstrate the action of simple machines to multiply effort force of distance. Three classes of levers were tested for the mechanical advantage they produced and how they make work easier. We'll go over this activity tomorrow before reviewing the simple machine homework and reviewing for Thursday's exam. Then - forces in fluids!
