We travel to a nuclear power plant to explain what happens inside an atom that undergoes fission and we show you how that process is harnessed to create electricity.
Segment 7B: Fission We travel to a nuclear power plant to explain what happens inside of an atom that undergoes fission and we show you how that process is harnessed to create electricity.Premiere Date: August 1, 2018 | Runtime: 00:08:39
-Define nuclear fission, and explain when nuclear fission occurs.
-Explain why large amounts of energy are released, and how the mass of the fission fragments are less than the mass of the fissioning nucleus.
-Discuss what a chain reaction is and when it occurs.
-Discuss how nuclear reactors work and what waste is created from them.
binding energy (E) - the amount of energy used to keep a nucleus together; equal to the mass defect times the speed of light, squared.
critical mass - the minimum amount of fissile material that can undergo fission needed to maintain a nuclear chain reaction.
fission - the process of splitting an atom into smaller, lighter atoms, releasing energy.
mass defect (Dm) - the difference in mass between the particles within a nucleus and the particles by themselves, not bound within a nucleus.
radioactive decay - the spontaneous emission of charged particles and/or energy from an atom.
strong nuclear force - the strongest of the four fundamental forces also having the shortest range, this attractive force holds the protons and neutrons in the nucleus of an atom together.
The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
