Veritasium – Why Gravity is NOT a Force
The General Theory of Relativity tells us gravity is not a force, gravitational fields don’t exist. Objects tend to move on straight paths through curved spacetime.

Three Right Hand Rules of Electromagnetism – Magnetic Force
Teaching electricity and magnetism is complicated by the challenge that the magnetic forces are perpendicular to the motion of the particles and currents. This requires a three-dimensional perspective which can introduce a variable of a “wrong” direction. To prevent errors, … Continue reading
