Have you ever been on a roller coaster, like the people in the picture above? If not, have you been an any amusement park ride? Or in a fast-moving car that stops suddenly? Have you ever wondered how airplanes stay in the sky?
Amusement park rides are exciting and thrilling because of the forces that are exerted on our bodies. Objects move, stop, and change direction between because of the invisible actions of forces. In this course, we will study different types of forces and their impact on objects! Our course will focus on the following guiding question:
How can we use the concepts of forces and Newton's Laws to describe and predict the movement of any object?
By the end of the course you should be able to:
- define force and the effects that a force can have on an object.
- describe different types of forces (gravitational, friction, elastic, magnetic, normal) and the effect that each force can have on an object’s motion
- draw free body diagrams and determine the magnitude and direction of the net force on an object
- state Newton’s First Law of Motion and explain how it relates to objects at rest and objects in motion
- state Newton’s Second Law of Motion and explain the relationship between force, mass and acceleration
- state Newton’s Third Law of Motion and give examples of force pairs
This course is intended for students at a high school level (Grade 8-10) who already have some knowledge about motion. It is assumed that students can describe there relationships between position, distance, time, velocity, and acceleration. A short review will be included within the introductory activities.
Each week you will complete the following:
1. Learning Activities which may include: videos, pHet simulations, readings, webquests
2. Discussion Posts which will include your own posting and responding to at least 2 of your colleagues posts
3. Weekly Assessment which could include MC questions, concept map creation, writing.
These weekly assessments can be changed, corrected and resubmitted after being given feedback (automatic in the case of MC questions, or from peers or the instructor)
The Final Assessment will be the creation of a video showing the movement of a body, the description of forces acting on the object, and showing Newton's Laws in action. More information can be found under the Tasks.
This course is intended to take approximately 5 weeks, assuming 1 hour per day or 5 hours per week.
Week 1: Introduction
Week 2: Types of Forces
Weeks 3/4: Free Body Diagrams and Newton's Laws
Week 5: Work on Assessment
The easiest ways to communicate with your classmates and the instructor are:
1. Discussion posts - This is the preferred method of communication as it allows everyone to be part of the discussion. Post any questions about the course, content, or assessments in the appropriate discussion post. Since we are working as a team, everyone is able to answer questions from classmates.
2. If you have an individual question, you may email the instructor who will attempt to respond within 24 hours.
