SPH 4U - Unit 3 - Electric, Gravitational and Magnetic Forces
Electrical, Gravitational and Magnetic Forces are all non-contact forces. The 'force' and 'energy' formulas for electrical and magnetic forces look similar too. We remind ourselves of what we learned about gravity (especially as we move into space beyond earth) as we looked at electrostatic forces (Chapter 8), magnetic forces (Chapter 9) and how the 2 interact (Chapter 9). At the very end, we look at how Maxwell was able to propose that light was a form of self-propogating electromagnetic wave!
