nuclear fission is the reaction that takes place in power stations: heavy atoms of unstable uranium-235 (i think) split into 2 smaller atoms and throw off neutrons. this is fission. if the neutrons are absorbed by other uranium atoms then these become unstable and split too, releasing some of their neutrons. if the neutrons are absorbed by even more uranium atoms then those become unstable and split too, releasing some of their neutrons. the cycle continues... this is a fission chain reaction. nuclear fusion takes place in stars: 2 hydrogen atoms join together to make a helium atom
Nuclear reactions are where the particles collide at high velocity, then flying off and extremely high speeds. Hiroshima as an example, a uranium bullet was fired into a large mass of other uranium and it had a devastating effect (destruction of city + radiation poisoning). The Russians built the biggest nuclear weapon named the Tsar bomb, Google it to find out more.
This is normally just called "nuclear energy". You can basically distinguish two types: 1) The energy that can be released in fusion, when light elements (such as hydrogen or helium) are combined into heavier elements (up to iron or so). 2) The energy that can be released in fission, when very heavy elements (such as uranium) are split into lighter elements (again, up to iron or so).

A nuclear reactor, such as a Pressurised Water Reactor
Nuclear power reactors - there are 104 operating in the US. See link below.
motion energy or nuclear energy
a star
The sun's energy is produced by nuclear fusion (not fission) at the core of the sun.
The sun, and other stars, which burn from nuclear fusion
Yes, radioactive decay results in the release of nuclear energy. The radioactive decay of an atom is the result of changes in the atom's nucleus, so energy released will be nuclear energy by definition.

motion energy or nuclear energy
No. Nuclear energy is a type of energy that is quite different from chemical energy.
a star
Nuclear is a exothermic nuclear processes. This is also known as nuclear energy or power.
Nuclear power stations.
Nuclear energy.
The sun's energy is produced by nuclear fusion (not fission) at the core of the sun.
The sun, and other stars, which burn from nuclear fusion
There are quite a few limiting factors for using nuclear energy. Nuclear energy is very expensive to produce for example.
