MONDAY, DEC. 1 ST 90 12/1/14 Mon. L.T.: I can analyze forces on an object and determine whether the forces are balanced or unbalanced. DO NOW: Draw arrows and use labeling to show the forces that are acting upon this apple falling from the tree. Reflection Q: Can I explain what normal force is? How well do I understand balanced and unbalanced forces? How well did I fill out my 4 boxes? 91 Title: Balanced and Unbalanced Forces Normal Force:Balanced/Unbalanced Forces: Slanted Surfaces:Challenge: Exceeding : Forces on apple the moment it falls on ground.
I CAN ANALYZE FORCES ON AN OBJECT AND DETERMINE WHETHER THE FORCES ARE BALANCED OR UNBALANCED. Normal Force: From the short video clip, what “rules” about normal force can you get? http://www.neok12.com/video/Types-of- Forces/zX6b5446515f574847567367.htm
I CAN ANALYZE FORCES ON AN OBJECT AND DETERMINE WHETHER THE FORCES ARE BALANCED OR UNBALANCED. Unbalanced/Balanced Forces : P. 281 in small green book: 5 mins, VL 2 to find out the difference between unbalanced and balanced forces: BalancedUnbalanced
DRAW ARROWS AND USE LABELING TO DESCRIBE THE FORCES ACTING UPON THIS BOX ON THE HILL. Slanted Surfaces:
DESCRIBE WHAT FORCE YOU HAVE AFFECTED BY DOUBLING UP THE BLOCKS. HOW HAS THIS CHANGED THE OVERALL BALANCING OF THE TOTAL “BLOCK”’ ON THE HILL? WHAT FORCE HAS CAUSED THIS TO HAPPEN? WHY? Challenge : Mini-Lab : 5 mins., VL 2. 1. Make a slanted surface using the books, binder, etc. so that 1 block stays in place but with 2 they slide. 2. Place 1 block on it. What forces are acting on the block? Are the forces balanced or unbalanced? How do you know? 3. Add another block on top of the other one. What force have we increased? How do you know? Are the forces balanced or unbalanced? I can give you tape to help secure the blocks together if you’d like…
