Net force is the vector sum of forces acting on a particle or body. The net force is a single force that replaces the effect of the original forces on the particle's motion.

Individuals and businesses producing renewable energy receive credits for each kWh they produce beyond their own needs

A net protection ring with U-shaped cross-section. The net pick-up is the ancillary component of the sterntube aft seal and its purpose is to prevent netting and fishing lines from entering the seal.

Means that any CO2 released into the atmosphere from human activity is balanced by an equivalent amount being removed.

Buildings that have been constructed with renewable energy features that allow self sustainability and balancing of energy from grid power and self produced energy.

Network analysis is the process of finding the voltages across, and the currents through, all network components.

An object with an absence of net charge is referred to as neutral.

A neutrino is a fermion (an elementary particle with spin of 1/2) that interacts only via the weak interaction and gravity.

The neutron is a subatomic particle, symbol which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.

Neutron activation is the process in which neutron radiation induces radioactivity in materials, and occurs when atomic nuclei capture free neutrons, becoming heavier and entering excited states.

Neutron capture is a nuclear reaction in which an atomic nucleus and one or more neutrons collide and merge to form a heavier nucleus.

Neutron embrittlement, sometimes more broadly radiation embrittlement, is the embrittlement of various materials due to the action of neutrons.

Neutron emission is a mode of radioactive decay in which one or more neutrons are ejected from a nucleus.

Neutron flux is a scalar quantity used in nuclear physics and nuclear reactor physics.

In nuclear engineering, a neutron moderator is a medium that reduces the speed of fast neutrons, ideally without capturing any, leaving them as thermal neutrons with only minimal (thermal) kinetic energy.

In applications such as nuclear reactors, a neutron poison (also called a neutron absorber or a nuclear poison) is a substance with a large neutron absorption cross-section.

Protecting the inside of the vessel from fast neutrons escaping from the fuel assembly is a cylindrical shield wrapped around the fuel assembly.

A neutron source is any device that emits neutrons, irrespective of the mechanism used to produce the neutrons.

The neutron detection temperature, also called the neutron energy, indicates a free neutron's kinetic energy, usually given in electron volts.

Neutron-induced swelling is the increase of volume and decrease of density of materials subjected to intense neutron radiation.
