Nt1310 Unit 4 Force Analysis

We want to understand the world around us. There are four theorised forces in our universe. These are: nuclear, strong, gravity and electromagnetic. These act very differently around us.

the four fundamental forces of nature

The weak force is responsible for; fission (radioactive decay), particles like muons, leptons and others with short lifetimes. This is the 3rd strongest force and only stronger than gravity. It counteracts the strong force. With a range is 10-18m which is smaller than an atom (10-15m). This exchanges with large bosons (bosons carry forces on objects) Z0, W+ and W- with huge masses-weakest range of all the four forces. Weak force also has a very short lifetime. This seems like a problem. However, due to Heisenberg’s Uncertainty …show more content…
This has the 2nd shortest range of 10-15m. This acts on quarks inside protons and neutrons equally; which are inside the nucleus-exchanging using bosons-called gluons. I suppose they “glue it together”. The neutrons help control the atom and when they get too close this force keeps them apart. Like a sad romance. An analogy often given involves selotape. First you feel nothing until, you get close and then it acts sticks “the strong force repels actually”. These two forces act inside of the atom. The outcome of these forces can be seen on the periodic table as the range is the size of a nucleus-this stops atoms from getting too big. In addition to this the larger atoms decay via the weak …show more content…
In Einstein’s theory of general relativity, gravity causes a distortion of space and time. This is the weakest of the force, but has an infinite range and acts by using gravitons. These have never been observed yet, sadly.
Magnetism and Electricity- were thought of as separate concepts. However, after observations and mathematical reasoning were shown to be linked as a single force. Famously, in 1820 Hans Christian Ørsted saw a needle being deflected by a battery cable and James Clerk Maxwell proved the two waves were perpendicular to each other.
Electromagnetism binds atoms and anything else in the universe that has charge e.g. protons, electrons, muons-[enter joke about neutron not getting charged in a bar]… This is the 2nd strongest force and also an infinite range using photons. Another way of looking at this would be a fridge magnet. This is many magnitudes stronger than gravity-something to think about. These two forces act outside of the
