Electric Field Visualizer

See the invisible field

Drag point charges around and watch the field arrows and potential shading respond — then drop a test charge and let it ride.

Scored investigations

Playing with a simulation is not the same as earning a point. These take your own measurements from this lab into a real AP free response, graded against the rubric.

Use field superposition to predict force and potential patterns

Unit 1 · Electric charge, field, and potential · Model reasoning · 6 pts
