Comments
ð Problem 1
Ø Force of gravity points down
Ø Many did not include a coordinate system or included an incorrect one (not tailored to the problem)
ð Problem 3: Must use components (clearly) of F in x and y directions
ð Problem 5 (first law): Unless no net external force acts on it
ð Problem 6 (second law): Many cannot clearly explain this law in words - you are memorizing equations with no idea as to the meaning (some cannot
distinguish the laws)
ð Problem 7 (third law): Some have no clue
ð Chapter 21, problem 4 not graded - flat could have been confusing to some
However, a loop lying flat is clear, a coil can be visualized as a series of loops one on top of the other, ...
