*  Few days before each lecture, there will be a lecture notes file in this site  so you can print it, read it and bring it with you to the lecture. 
*  Each week you will be given homework for submision. The homework will be given at the end of each lecture notes file. You should submit it untill the next lecture to Gideon's mail box at building 30 2nd floor (mail box No. 115)  make sure you write your name and ID clearly on it. 
*  Each week the grade for the home work will be devided equally between all the questions with a total of 20 points. For example, if you have 4 question in a certain week, the grade for each question is 5 points. Each well written answer will get the full points, even if it is not correct. In order to get the full grade for the homework, it is necessary to submit 10 problem sets, but whoever submits more can improve the final grade! 
*  There will be a quiz (bochan) at about the midsemester. 
*  The final grade will be calculated as follows: Homework: 20% ; Quiz: 20% ; Final exam: 60% ; 
Lecture No.  Topics  Lecture notes and homework file  Notes  Date of submission 
1  *
From atoms to planets: scales of size. * The role of atoms in a geography course.
* Pythagoras theorem and square
roots.
* Pythagoras theorem and some
basic
physics. 
Lecture 1  Questions 1,2,3
are a must. Questions 4,5: you can choose wether to submit it this week or the next. But remember that next week there will be another problem set. 
10.11.05 
2  * Momentum * Mass * Weight * Mass and energy 
Lecture 2  *Whoever didn't submit Questions 4 and 5 from last week must submit them this week. * In question 2 the 2 Km should be 2 Kg, and the velocity of the 4 Kg body is of course 5m/s. * In question 3, the bullets velocity units should be m/s. 
17.11.05 
3  * Force and Newton's law of motion * Gravity 
Lecture 3 Quiz (bochan) 
* Quiz: In question 1 the frame is a square so that the
length that is given is both the length and the width. Quiz rules:(1) You have one week to submit the quiz. (2) You may not receive help from anyone else. (3) You should hand the answers to Prof. Faiman at the next lecture.
