Week one standards this summer were the following:
#1: I can re-express quantities using different units
#2: I can distinguish among position, distance and displacement
#3: I can relate an object’s acceleration to how its velocity changes
#4: I understand the direction and signing conventions for acceleration during free-fall
Next time, I want something more like: I can distinguish between average velocity from change in velocity.
There are just too many times that we are thinking through problems by considering these kinds of quantities
1/2 (Δv) (Δt)
The reason I am saying this is because on our first exam, much of the feedback I gave out was about the distinction.
