Electric Field Strength

Mr. Anderson explains electric field strength in AP Physics Essentials video 27. He uses simulations to demonstrate how increasing charge affects electric field strength, showing a direct relationship between the two. Positive charges push away, while negative charges attract. The video uses arrows to represent field strength and employs a PhET simulation for quantitative analysis, illustrating the concept with measurable data.

What is the significance of using arrows to represent electric field strength?

Describe what happens to the electric field strength when charges are removed from the simulation.
