terminal velocity	volume	weight

Chapter 5 Objectives:

When you have completed chapter 5, you should be able to:

0. ... distinguish between "directly proportional", "inversely proportional" and "equal to."
1. ... recognize Newton's Second Law and discuss the relationship between net force on an object and its acceleration, and between the mass of an object and its acceleration.
2. ... distinguish among mass, volume, and weight.
3. ... discuss the role of friction forces in everyday motions.
4. ... discuss and apply the relationship between mass and weight.
   1. ... find the weight of an object given its mass (and "g").
   2. ... find the mass of an object given its weight (and "g").
5. ... solve numerical problems involving force, mass, and acceleration of objects.
6. ... define pressure and distinguish pressure from force.
7. ... recognize and apply the concept of pressure in various situations.
8. ... explain why any two objects fall with the same acceleration in the absence of air resistance (free fall).
9. ... define terminal velocity and discuss how objects reach a terminal velocity when falling in a fluid.

Possible Misconceptions to Correct:

Do you believe that any of the following statements are true? They AREN'T! When you finish Chapter 5, you should understand that each of these statements is FALSE, and WHY.

• WRONG: Weight and mass are the same.
• WRONG: Mass and volume are the same.
• WRONG: Pressure and force are the same.
• WRONG: Heavy objects always fall faster than light objects.
• WRONG: Objects have no weight in a vacuum.
