Chapter 4: Forces in One Dimension

Forces in One Dimension:

In this unit, students will learn that exerting a net force on an object causes that object's velocity to change. We will also discuss and evaluate forces and how they can be exerted either by direct contact with another object or in some cases via a field, such as gravity. Newton's laws, which describe how force affects velocity, will be evaluated and applied to everyday situations.

Power Standards:

Students will be able to read and solve physics problems by writing down what is given in the problem, choosing the correct equation, and calculating the correct answer with the appropriate unit.
Students will be able to read laboratory investigations, follow the directions, use laboratory equipment properly, follow safety instructions, and analyze the data to help apply physics concepts learned.
All students will be able to explain velocity, acceleration, and forces for objects in one-dimensional motion. Students will use graphs, free body diagrams, written expression, and laboratory investigations to apply those concepts to everyday life.

Learning Targets:

Learning targets are what the students will be assessed on.

Physics Knowledge:

PK 4.1 - I understand the action at a distance and the contact forces and can identify them in various situations. Chapter 4, Lesson 1
PK 4.2 - I can properly draw and label a Free-Body diagram, showing all forces acting on a system. Chapter 4, Lesson 2
PK 4.3 - I can determine the net force on an object and know when an object is in equilibrium. Chapter 4, Lesson 2
PK 4.4 - I understand and can apply each of Newton's three laws of motion. Chapter 4, Lesson 3
PK 4.5 - I know the difference between mass and weight. Chapter 4, Lesson 4
PK 4.6 - I know what terminal velocity means and how it relates to the forces acting on an object falling through the air. Chapter 4, Lesson 4

Math:

M 4.7 - I can use the five steps to solve problems with the equations that we have learned in this chapter (F, m, a, and g.). Chapter 4, Lesson 4
M 4.8 - I know the abbreviations/units for mass, acceleration, acceleration due to gravity, and force. Chapter 4, Lesson 4

Standards Based Grading Scale:

All of the above learning targets will be assessed with the following scale:

4 - Advanced. The learner has demonstrated a high level of conceptual and procedural understanding of the specific knowledge and skills.

3 - Proficient. The learner has demonstrated understanding of the specific knowledge and skills.

2 - Beginning. The learner is emerging but does not yet demonstrate understanding of specific knowledge and skills.

1 - The learner has provided some evidence, but not enough to assess proficiency.

0 - The learner has provided no evidence of the skill.

Learning targets will be added to MiStar at the beginning of the chapter and grades (0-4) will be entered as the students meet with the teacher and demonstrate their understanding of the learning targets. Learning target grades may not be added at the same time. If there is a blank, then the student may not have had the opportunity to demonstrate thier knowledge yet. A grade entered as zero means that they had the opportunity to demonstrate their knowledge and they chose not to.
