Thurs-Day 2
Physics- began our new unit on Dynamics, in which we will study the laws that relate Force to Mass to Acceleration.
These laws were discovered and mathematically quantified by Isaac Newton, one of the all-time genius scientists whose impact on the world is still felt every day.
We discussed his description of the relationship between mass and "inertia", which is the RESISTANCE to change in velocity. An object that has a lot of MASS will naturally have a lot of resistance to changing its speed and/or direction, whether that mass is at rest or moving.
AP Chem - we did a Dalton's Law of Partial Pressure/Ideal Gas Law problem involving a gas collected over water, a process that automatically introduces water vapor as one of the gases contributing to the total pressure.
We then did a gas stoichiometry problem involving a conventional "two-bulb" setup in which the gases are initially separated, each with unique conditions, and then combined and (usually) reacted.
I will post MANY review problems with fully detailed solutions.
