Nuclear Fission and Fusion - Difference and Comparison
Nuclear fusion and nuclear fission are different types of reactions that release energy due to the presence of high-powered atomic bonds between particles found within a nucleus. In fission, an atom is split into two or more smaller, lighter atoms. Fusion, in contrast, occurs when two or more smaller atoms fuse together, creating a larger, heavier atom.
Cold fusion - Wikipedia
Cold fusion is a hypothesized type of nuclear reaction that would occur at, or near, room temperature would contrast starkly with the "hot" fusion that is known to take place naturally within stars and artificially in hydrogen bombs and prototype fusion reactors under immense pressure and at temperatures of millions of degrees, and be distinguished from muon-catalyzed fusion.
Nuclear Fusion - Definition, Occurrence, Examples
Nuclear fusion is when two or more atomic nuclei fuse to form a single heavier nucleus. Every star in the universe, including the sun, is alive due to nuclear fusion. It is through this process that they produce an enormous amount of heat and energy.
Electromagnetism - Magnetic fields and forces | Britannica
Electromagnetism - Electromagnetism - Magnetic fields and forces: The magnetic force influences only those charges that are already in motion. It is transmitted by the magnetic field. Both magnetic fields and magnetic forces are more complicated than electric fields and electric forces. The magnetic field does not point along the direction of the source of the field; instead, it points in a
Motion – The Physics Hypertextbook
The study of motion without regard to the forces or energies that may be involved is called kinematics. It is the simplest branch of mechanics. The branch of mechanics that deals with both motion and forces together is called dynamics and the study of forces in the absence of changes in motion or energy is

What is mechanical energy? - Definition, Conservation Of
Mechanical energy is the sum of kinetic energy and potential energy in an object that is used to do a particular work. In other words, it describes the energy of an object because of its motion or position, or both. Let us consider the example of an ideal simple pendulum (friction-less).
Next Generation Science Standards
The Next Generation Science Standards (NGSS) are K–12 science content standards. Standards set the expectations for what students should know and be able to do. The NGSS were developed by states to improve science education for all students. A goal for developing the NGSS was to create a set of research-based, up-to-date K–12 science standards.[PDF]
