Simulation of coulomb interaction effects in electron. Coulombs law main concept coulombs inverse square law is a law of physics that describes the electrostatic interaction between two electrically charged. Virtual chemistry and simulations american chemical society. Learn how the placement of charges leads to electric field and electric potential patterns in nearby space using our interactive simulation.
The coulombs law interactive allows learners to explore the force of attraction or repulsion between two charged objects. Application of coulombs law, with vernier video simulation. In a coulomb simulation, we assign forces among the set of edges and the set of nodes. This week you will be completing the coulomb s law lab pg. The simulation includes the modelling of cathode emission and the effects of volumetric space charge. In the present paper we describe the existing software and explain how we have extended this software to include the effects of discrete coulomb interactions between the electrons as they travel from the cathode surface to the exit of the gun.
The supplied files are for datastudio software but they can also be opened using pasco capstone software. The software sets a series of 11 lab activities, and in each lab. The quantity of charge on the objects can be varied by dragging a slider. Coulomb, a powerful 3d electric field design and analysis software featuring our innovative boundary element method bem technology, well suited for applications where the design requires a large open field analysis and exact modeling of the boundaries. Chemistry moves from the lab and the classroom to the computer, as working in a virtual chemistry laboratory and viewing simulations provide additional ways of learning chemistry. We will be using logger pro software on the lab computers to complete this lab.
