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
Charges & fields observations
https://phet.colorado.edu/sims/html/charges-and-fields/latest/charges-and-fields_en.html This great learning object from PhET is great tool for discussion in the Physics classroom, as well as a powerful simulation of actual values. Here are three interesting screen shots that can be used as basis for discussions. This … Continue reading

PhET – Charges and Fields
Arrange positive and negative charges in space and view the resulting electric field and electrostatic potential. Plot equipotential lines and discover their relationship to the electric field. Create models of dipoles, capacitors, and more! (Choose the fullscreen option down the … Continue reading

Gravitational energy vs height
Open the embedded graph to change the value of h and calculate the gravitational potential energy / kg at different heights. Can you estimate the kinetic energy needed to escape the Earth’s gravitational field?
