In this course you will learn about:
This video explains about coefficient, constant, variable and exponents. Useful for introductions to the topic and/or extension work.
Introduction to magnetism: Wikipedia article that provides an overview of the concept.
The force that acts across the air gaps between magnets is the same force that creates wonders such as the Aurora Borealis. In fact, magnetic effects pervade our lives in myriad ways, from electric motors to medical imaging and computer memory. In this chapter, we introduce magnets and learn how they work and how magnetic fields and electric currents interact.
An exploration of how the area under a force vs. position graph equals the work done by the force and solves some sample problems.
What exactly is energy? How can changes in force, energy, and simple machines move objects like roller coaster cars? How can machines help us do work? In this chapter, you will discover the answer to this question and many more, as you learn about work, energy, and simple machines.
An exploration through some example problems on the concept of work.
