This Area of Study looks at three fields: Gravitational, Electric and Magnetic. Resources for the other fields are available at Electric Field and Magnetic Field.

'Teaching Advanced Physics' is a UK resource for teachers new to teaching physics. It assumes only a limited access to equipment, resources, and advice from experienced colleagues. The section on Fields covers Gravitational and Electrical Fields and Electromagnetism. It consists of 16 episodes, each of which is for one or two 60 min lessons. Content of each episode is a lesson plan with a description of the content covered, with points to emphasise in discussion, along with activity or question sheets for the students.
This applet by Walter Fendt displays the elliptical nature of planetary orbits. The display features the sun and the planet. You can choose to show any of all of the following the orbital path, the axes, and the lines to the foci. You can move the planet to other points in the orbit with your cursor. You are able to choose any of the planets or Halley's comet. The display also includes the semi-major and semi-minor axes and the eccentricity. The distance from the sun, max, min and for where the planet is are displayed in A.U.'s. You can also design your own orbit by entering values for the semi-major axis and the eccentricity.
The display features a planet going around the sun. You can add two sectors of equal area with the time in each recorded each time the planet passes through each. The location of the areas in the orbit and their size can be adjusted. Similarly you can select the show the velocity vector on the planet as it revolves. You can select any of the planets or Halley's comet or design your own orbit. The display also gives the planet's distance from the sun and the current velocity, as well as max and min values. There is a slow motion option which is useful showing the velocity vector of Halley's comet.
Applet visualises the gravitational force that two objects exert on each other. You can adjust properties and spacing of the objects to see how changing the properties affects the gravitational attraction.
