NOTE: The exam will cover major concepts from chapter 13 and 14, and some from chapter 12.
d s t m D v F = m • a Chapter 12
• How is a reference point used to show motion?
• How do you calculate speed? average speed? velocity? acceleration?
NOTE: See Appendix on pp. 546–547 for review of average speed, acceleration, and net force. You
will need to know the formulas for speed and acceleration.
• Practice using the 3-variable speed pyramid, when two of the variables are given in a
problem. What would be the correct SI units to use to describe speed?
• What is force? What is Net Force?
• Compare balanced and unbalanced forces? What is the SI unit that describes force?
• Describe the forces of compression and tension.
• What two properties do all forces have? Use vector diagrams to determine net force.
• What is friction and how can it be increased? How can it be decreased?
Chapter 13
• What is gravity and what does the “Law of Universal Gravitation” mean?
• How do mass and distance affect gravitational force?
• What is the difference between mass and weight?
• Why will a baseball and a marble fall at the same rate? What is 9.8 m/s2?
• What are the two forces that combine to determine the NET force on a falling
object? In what directions do these two forces act?
• Explain terminal velocity
• What is free fall and what does it have to do with a vacuum?
• Why is projectile motion a curved path? What are the directions of the forces?
• Explain how the planets are kept in orbit around the sun. (See Figure 8 on page 382)
• Describe and understand Newton’s 3 Laws of Motion (review the “Newton’s Laws of
Motion” worksheet.)
✪ Inertia
✪ F=m•a
✪ Balanced vs. unbalanced forces
✪ Action/reaction force pairs
Chapter 14
• What is a fluid and how does a fluid behave?
• What is the relationship between atmospheric pressure and depth?
• What is the relationship between water pressure and depth?
• Explain how pressure differences cause you to exhale, and cause a tornado.
• What is buoyant force?
• What determines if something will sink or float?
• How do you determine density? What are the ways to determine volume?
• What happens to density if you change the shape, mass or volume of an object?
