2. SEMESTER GRADES POSTED VOCABULARY QUIZ FRIDAY HOMEWORK DUE TOMORROW

3. LW #1~CHANGING FORCES PROBLEM: HOW CAN FORCES BE COMBINED TO INCREASE AND DECREASE MOTION? PART A: 1.Use your textbook or CW# 2 to answer the following questions in complete sentences: a)Explain how BALANCED FORCES affect motion b)Explain how UNBALANCED FORCES affect motion

4. PART B: COPY THE CHART BELOW (USE THE ENTIRE PAGE FOR THE CHART) BLOCK MOVING SLOWLY BLOCK MOVING RAPIDLY BLOCK NOT MOVING

5. The Set-up 1)Using the books and whiteboard, set up a ramp that is EXACTLY 20 cm high. 2)From the bottom of the ramp, measure a distance of EXACTLY 50 cm long and mark it

6. YOUR CHALLENGE… WITHOUT CHANGING THE HEIGHT OF THE RAMP, USE ANY OF THE SUPPLIES PROVIDED TO CREATE THE FOLLOWING SITUATIONS:
