SHS2 Physics · Semester 1 Week 20: Electrostatics

Lesson notes

Learning Objectives

Indicator: 2.3.1.LI.1 - Explain and show how an electric field is represented and their characteristics

By the end of the lesson, learners can:

Define an electric field as the region around a charged body where another charge experiences a force.
Explain that electric lines of force (field lines) are used to represent electric fields and describe their key characteristics.
Draw the electric field patterns for a positive charge, a negative charge, and a pair of opposite charges.
Interpret the spacing and direction of field lines to compare field strength at different locations.
Create a short presentation comparing electric field lines with magnetic field lines, using a simulation or diagrams.
