Forces and Motion Commotion 2012 name______

Textbook reference pages: 16-72 (selected pages) hour______

Objectives: On quizzes, students should be able to:

Part A: Motion and Speed of Objects

1. Describe and measure motion using the concept of a reference point.

2. Describe and measure speed and be able to calculate speed.

(Know what 2 factors –distance and time—on which speed depends.)

3. Graph motion showing changes in distance as a function of time

(This means know how to graph speed!)

4. Demonstrate the difference between speed and velocity.

5. Understand the concept of constant motion or constant speed.

Part B: Accelerating Objects

6. Understand and describe how constant speed differs from acceleration?)

7. Describe the motion of an object as it accelerates

8. Define the 3 ways an object can accelerate.

9. Calculate and graph the acceleration of an object.

10. When you look at a line graph, be able to identify what the types of motion are shown.

(constant speed compared to acceleration)

(See pages 24 and 38 for examples of these types of graphs.)

Part C: Newton’s 3 Laws of Motion

11. Define, give, recognize, and understand examples of both balanced and unbalanced forces.

12. Define, give, recognize, and understand examples of Newton’s First Law of Motion.

13. Define, give, recognize, and understand examples of Newton’s Second Law of Motion.

14. Use the formula that defines Newton’s Second Law of Motion to calculate:

acceleration, force, or mass of an object

15. Understand that friction is a force that opposes motion.

16. Define weight in terms of mass and gravity.

17. Explain the law of conservation of momentum.

18. Define, give and recognize examples of Newton’s Third Law of Motion.

19. Explain how artificial satellites from Earth must achieve escape velocity to be launched.
