Forces and Mechanical Energy

Presentation

“Forces and Mechanical Energy” is the next course after “Optics and Kinematics.” While kinematics studies motion, dynamics studies the causes of this motion: forces. Forces are indispensable for doing work and, in order to work, you need energy. In this course, the emphasis is on mechanical energy and on one of the most important and most widely used laws in the study of the physical world, the law of conservation of energy.

Content

The six learning sequences in this learning guide will help you to acquire new knowledge and apply it competently. The subject-specific competency “Seeks answers or solutions to problems involving physics” will be required to carry out tasks in experimental activities, such as measuring the force needed to set a block of wood in motion on various rough surfaces. The subject-specific competency “Makes the most of his/her knowledge of physics” will be required to complete tasks in complex and realistic situations, such as recommending the appropriate motor to operate a stairlift. For both of these competencies, you will apply the subject-specific competency “Communicates ideas relating to questions involving physics, using the languages associated with science and technology” by explaining results or justifying choices. A self-evaluation activity and four scored activities will help you to take stock of what you have learned and how well you apply this knowledge.

Recipients

Anyone wishing to obtain a Diploma of Secondary Studies (DSS) and to continue their studies at the college level in certain general education or technical programs.

Prerequisites

Optics and Kinematics (PHS-5061-2).
