5 other physics equations that everyone should know
On the right, kDescription Boltzmann is fixed and called omega (ω) The number of “microstat” may. Let me explain with an example: Say I have four coins and four. How many different ways can I share these coins? Well, the two intense cases are that everyone receives one coin or all four coins go to one person. Overall, there are 35 possible distributions. These are microstates (ω). So you can think of possible energy measures between the particles while keeping the whole energy the same.
If I release a basketball, its gravitational potential energy decreases with a fall and its kinetic energy increases – key energy is maintained. But it does not bounce as much as it started. The reason is that some energy as heat is destroyed by impact. The ball is slightly warm. When we consider this thermal energy, we realize that the energy is still maintained. But the entropy is more.
But what if the ball gets The colder And bounce Higher? This means that the thermal energy decreases and the kinetic energy increases. Energy Still Maintain, but in this result, the entropy decreases. This is actually possible, but you can run this test until the end of time and never get the result.
Here’s another interesting example. Imagine put the ice in a glass of warm water. Could the water get warmer and the ice becomes colder? Again, the possibility is non -zero, but it seems unlikely. The Boltzman Formula says the more possible microstates there is the greater the entropy.
Finally, this leads to the second law of thermodynamics, which states that the entire entropy of a closed system can only increase over time, or at least never decrease. So, like, your desk is just more ridiculous and ridiculous unless you open the “system” and “do the job” – which you remember, it means adding energy. Unfortunately, the world is a really isolated system, so it can only end one way – overall losing all structure and life.

This equation is used in many of our modern devices because it deals with electricity. The Operation Law Interesting between Energy Energy Changing Electrical Properties (Δv) In some elements in a circuit and electric current (I) Move through that element. Since saying “change in electrical potential” is boring, we often call it “voltage”, as it is measured in the volt. The proportion between the voltage and the stream of resistance is called (Letter);); No wonder it is measured in the units.
