i need help
sir can i get some help please, because i have got no idea about what to write up in this second note can i get some help please.
lecture-note
just wrote down what you learned in the class, and show how much you have understood. Or if you could not understand some parts, ask in the lecture-notes, and show where and why you do not understood.
I do not understand some of the notation
I know Sigma F is the sum of the forces but does sigma Fi mean sum of all Forces in the horizontal direction. I do not feel you explained this very clearly.
force vectors
Sigma F is the summation of forces. Notice that forces are vectors. Therefore, Sigma Fi = 0 can be applied to any direction.
Come to my office if still confused.
When are the notes due in
Is it just lectures 1 and 2 that are due in today or also lecture 3
