This SPH4U course enables students to deepen their understanding of physics concepts and theories. Students in SPH4U will continue their exploration of energy transformations and the forces that affect motion, and will investigate electrical, gravitational, and magnetic fields and electromagnetic radiation. Students will also explore the wave nature of light, quantum mechanics, and special relativity. In this SPH4U course they will further develop their scientific investigation skills, learning, for example, how to analyse, qualitatively and quantitatively, data related to a variety of physics concepts and principles. Students in SPH4U will also consider the impact of technological applications of physics on society and the environment.
Course curriculum
Inside %course-code%: from circular motion to relativity
The engineering physics credit
Dynamics, energy and momentum, fields, waves and modern physics — the five units of study, each explored qualitatively and quantitatively, as university engineering and physical-science programs expect.
A lab in every unit
Circular motion, elastic energy, magnetic force and the double slit — you prepare, carry out and write up a lab investigation in each unit, submitted as a video report and a written report.
Modern physics, made approachable
The evidence for quantum mechanics and Einstein’s special relativity, and how new models change scientific thought and lead to new technologies.
Physics applied to real problems
A short research project in each unit applies the concept or law you just learned to a real-life problem, and looks at the social and environmental impact of the technologies that use it.
Simulations and conversations — physics you can test
Interactive simulations in every unit let you change the variables and watch the physics respond, and a conversation with your teacher at the end of each unit lets you talk through your thinking, not just submit it.
