Physics Chap 4 Numbered Heads Review

1. Form into the designated groups

2. Take out one full sheet of paper per group and list the name of the group at the top. Then list the names of the group members and place numbers next to each name (1, 2, 3…..If four members then write 4 also). It doesn’t matter who gets what number.

3. Hand the paper to the instructor. It will be used for ASSESSMENT and graded.

4. Begin reviewing/ LEARNING the listed CONCEPTS. Make up sample questions related to the concept. Try to imagine what question the teacher will ask. Time is limited; so don’t waste it!

5. Once you understand the concepts yourself locate the group members who do not understand  by assessing them. Do not ask yes or no ASSESSMENT questions.

Good ASSESSMENT. “Sam, could you show me how to do number three on the list?”

Poor Assessment. “Do you guys all know it?”

Now teach them how to answer the questions you have formulated.  

6. When the instructor calls a number randomly (ex. = 3) the three will go to a designated area alone and respond to a similar question. Make sure they have something to write with and a CALCULATOR. After they leave begin studying the next set of concepts for the next round.

7. After a short amount of time the person will then return to the group and their answer will be graded by the TEACHER and given to the entire group as a communal score.

8. The returning group member may be called again so they should receive extra instruction to help get caught up.

9. The scores are added at the end to determine WINNERS. The top three groups receive extra points on the test.

1.      Explain the relationship between the motion of an object and the net external force acting on the object.  Understand and be able to apply Newton’s First Law to situations involving an object at rest or in motion.

2.     What is net force?  Draw and analyze a force diagram to determine net force.

3.     What is equilibrium?  What are the two ways in which an object can be in equilibrium?

4.     Be able to determine the acceleration of an object of known mass caused by a known net force (Newton’s Second Law). 

5.     Be able to identify action-reaction pairs of forces and apply Newton’s Third Law to determine the magnitude and direction of the forces.

6.     Explain the difference between mass and weight.  Be able to calculate weight in Newtons from a mass in kg.

7.     What is normal force?  Be able to determine the magnitude and direction of normal forces.

8.     Explain the difference between static and kinetic friction.  Use coefficients of friction to calculate frictional force.  Be able to determine frictional force for an object in equilibrium or an object with a known acceleration.
