Neutrons have a zero charge but consist of mass.
If more microscopic technology is invented, then more things in the world can be discovered. Likewise, if a new element is discovered, then people can use it in their technology.
The work-energy theorem states that the net work done by the forces on an object equals the change in its kinetic energy.
