Construct at least 5 notes/facts Answer questions 1-3 on page 25 Vocabulary Puzzle – Quiz Today! Continue Working on Concept Layer Due Friday of This WEEK

3. Objective Identify and describe how forces acting upon an object affect its motion. Demonstrate an understanding of the concept of multiple forces reinforcing or opposing each other to produce a resultant force.

4. Objective in Layman’s How is Motion related to forces acting upon an object? What happens when there is more than one force acting upon an object?

8. Essential Questions 2. What is a Force? What can it do?

9. Essential Questions 3. What happens to an object when only 1 force acts upon it?

10. Essential Questions 4. What happens to an object when more than 1 force acts upon it?

11. Essential Questions 5. Why is Friction good and bad?

12. Bell Work Calculate the Slope of a line that has a Rise of 10 meters And a Run of 3 seconds Is this a Steep or Shallow line?

13. Terms Interpolation-Look within points of data to predict an outcome What do you think would be the value of 1.75 (X-axis) for Y-axis?

14. Terms Extrapolation-Looking beyond known data points to make a prediction What do you think would be the temperature at a value of 70 mins?

21. Terms What do you think would be more accurate for predictions? A.InterpolationB. Extrapolation Interpolation is more accurate for predictions due to the use of known data on either side of the prediction. Extrapolation is not as accurate, b/c the data points known might not account for any unknowns at various extremes.
