PHYSICS: Good job thinking through the equilibrium problems today. A couple of things that work for me – draw them first. Then go back through and separate resultants into components. If an object is in equilibrium, then there are no net forces – all the forces in the x direction balance – everything left equals [...]

PHYSICS: Great job on the inertia balance lab yesterday! Here’s the lecture from Thursday on introduction to forces and Newton’s First Law. FYI – if you like to see it, I’ve put the Julius Sumner Miller video on the Law of Inertia in the VodPod collection – check it out below!
