Charges and Fields Remote Lab Introduction to Static Electricity (This lesson is designed for a student working remotely.) This lab uses the Charges and Fields simulation from PhET Interactive Simulations at University of Colorado Boulder, under the CC-BY 4.0 license. Learning Goals: Students will be able to A. Determine the variables that affect how charged bodies interact B. Predict how charged bodies will interact C. Describe the strength and direction of the electric field around a charged body. D. Use free-body diagrams and vector addition to help explain the interactions. E. Compare electric fields to gravitational fields. Review your understanding: 1. Two balloons were rubbed on a sweater like in the Balloons and Static Electricity and then hung like in the picture below. Explain why you think they move apart and what might affect how far apart they will be
