The Charged Particle Motion Simulation Demonstrator in an Electric Field simulates the motion of charged particles in an electric field The instrument consists of switch, power indicator, analog screen, acceleration knob, deflection knob Turn on the power switch and wait for the self-test to complete, simulate particle movement, and adjust the acceleration knob to make the particles move in a uniformly accelerated straight line. Adjust the deflection knob Appropriate physical activities and research are not only fun, but can also enhance students' observation skills, stimulate questions, and connect the content of the book with real life We have provided some simple experimental ideas. In our pictures, we can use this to open up our ideas to understand some hypotheses about Charged Particle Motion
