Module 3—Effects of Force on Velocity
In This Module
Lesson 1—Newton’s First and Second Laws of Motion
In this lesson you will explore and apply Newton’s first and second laws of motion as they relate to unbalanced forces and changes in velocity.
You will explore the following questions:
- How is the motion of an object affected by forces applied to it?
- How do unbalanced forces affect the motion of an object?
- How do Newton's laws help explain why motion occurs?
Lesson 2—Newton’s Third Law
In this lesson you will explore the implications of Newton’s third law.
You will focus on the following essential questions:
- How do Newton's laws help explain why motion occurs?
- How do you find a reaction force?
- How does friction affect moving objects?
Lesson 3—Normal Force and Friction
In this lesson you will see a brief introduction to free-body diagrams and explore the nature of the normal force and its relationship to weight. You will also graphically determine an expression for kinetic friction and calculate kinetic, static, and rolling friction in a variety of situations.
You will explore the following questions in this lesson:
- How does friction affect moving objects?
- How does friction affect making an object move?
- How do free-body diagrams, vector analyses, and Newton's second law help solve moving-object problems?
Lesson 4—Free-Body Diagrams and Net Force
In this lesson you will construct labelled free-body diagrams for objects in a variety of physical situations. You will use these diagrams to derive net force equations that describe the observed acceleration of objects.
You will explore the following questions:
- How is the motion of an object affected by the forces applied to it?
- How do unbalanced forces affect the motion of an object?
- How do free-body diagrams, vector analyses, and Newton's second law help solve moving-object problems?
Lesson 5—Solving Net Force Problems
In this lesson and the associated labs you will learn to apply Newton’s second law and free-body diagram analysis to solve linear (one-dimensional) and non-linear (two-dimensional) net force problems.
You will explore the following question:
- How do free-body diagrams, vector analyses, and Newton's second law help solve moving-object problems?
