5 More physics equations should know everyone

On the right side, your_for It is called the Bolktmann Thabet, and the omega (ΩIt is the possible number of “microstate”. Let me explain with an example: Say I have four coins and four people. How many different methods can I share these coins? Well, there are two extremist cases that each person gets one currency or that all four currencies go to one person. In total, there are 35 possible distributions. This is Microstates (Ω). So you can think about it as possible energy arrangements between the molecules while maintaining total energy as it is.

If you drop basketball, its potential gravitational energy decreases with its fall and increased kinetic energy – natural energy is preserved. But it does not bounce on a height as it started. This is because some energy leaks as a heat on the effect. The ball is a little heating. When we take this thermal energy in mind, we find that the energy is still preserved. But the entropy is higher.

But what if the ball happens Coldness Bounce higher? This means that the thermal energy decreases and increases the kinetic energy. Energy will Still It is saved, but in this result, entropy is reduced. This is already possible, but you can run this experience until the end of time and do not get this result.

This is another fun example. Imagine putting ice in a cup of warm water. Is it possible that the water becomes warmer and the ice becomes cooler? Again, the possibility is not zero, but it is unlikely unlikely. Bolktmann’s formula says that the more Microstates there, the more intrusion.

At that time, this leads to the second law of thermal dynamics, which states that the entire entrance of the closed system can increase over time, or at least it can never decrease. Thus, for example, your office will not get chaos and more chaos, unless you open this “system” and do some “work” – which he remembers, meaning adding energy. Unfortunately, the universe is a truly isolated system, so it can only end in one way – in the total loss of the structure and life.

4. Om Law

This equation is used in many of our modern devices because it deals with electricity. The Om Law gives a relationship between the change in electrical energy (Δv) Through a component in the circuit and electrical current (I) Move through this element. Since it is fun to say “change in electrical capabilities”, we simply call it “voltage”, as it was measured in Volt. The constant is called the voltage and the resistance current (P); It is not surprising that they are measured in Om units.
