Forces of Nature – The Weak Nuclear Force
The weak nuclear force is indeed the weakest of the four forces of nature. It is responsible for the nuclear decay of atoms and there are three types of decay that take place: 1) Beta minus decay – A neutron decays into a proton and emits an electron and an electron anti neutrino. 2) Beta…

Forces of Nature – The Strong Nuclear Force
The strong nuclear force is indeed the strongest of the Four Forces of Nature, but it only works at the heart of the atom and has a very small range, just 10-16 metres. This range is only just bigger than a proton or neutron and it comes from the gluons that hold the innards of…

Forces of Nature – Electromagnetism
The electromagnetic force bears some resemblance to gravity in that it is infinite and obeys the inverse square law. However, this is where the similarities end. The electromagnetic force is 10^43 time stronger than gravity and, more importantly is has both a positive and negative charge. This positive and negative charge lead to important implications…

Forces of Nature – Gravity
Gravity is the most obvious of the four forces of nature. It is what holds our feet on the ground, the atmosphere in place and keeps Earth orbiting the Sun but gravity is an attractive force only, anti gravity is the subject a science fiction. Gravity has an infinite range but is the weakest of…

Four Forces of Nature
In nature there are four fundamental forces that control everything in the in the universe. They are:– 1) Gravity. This is the force that keeps our feet on the ground and is experienced by everything. 2) Electromagnetism. This keeps your magnets stuck to the fridge but also keeps the molecules in your body together to…
