Question: Jenny wants to treat two of her friends out. She wants to know if she should take them to a movie, then hold a party at her home right after, or take them to a movie and hold the party next week. Assuming the week is a school week, both events let them gain equal amounts of energy, and Jenny lives very close by to the theater, which option would make Jenny's friends the happiest?
Okay, so for this problem, let me explain a few things. First of all, this isn't really a real problem involving real energy, but I'm going to prove the answer to you using "Happiness Energy" and the laws that go along with it in a way similar to how one would solve a physics problem.
The laws:
So let's start with the law of energy, that even applies to happiness energy, HE (and I know that's similar to the abbreviation for helium in the periodic table, but that's not what it means in this case). The law is energy cannot be created nor destroyed. This is a really important law, and similarly, HE can't be created or destroyed either. Another form of energy, however, can transform into happiness energy. A common example is sadness energy, SE (which does not refer to Selenium), which often transforms to happiness energy when one feels happy. However, there's also madness energy, the energy of guilt, selfishness energy, etc. etc, which I may cover in later problems. This leads to a problem, because that means HE does not just come from SE, but from other forms of energy as well. Therefore, there is only one law that sums up the conservation of energy theory, which I'm getting to.
You've heard of mechanical energy conservation in a closed system when friction can be ignored, right? If you haven't, then here it is:
So since first answer is greater than the second, we can conclude option one of going out to a movie then a party right after would make her friends a a lot more happy.
And that's how to solve a problem using basic laws of physics! Here's your professor, signing out!

You've heard of mechanical energy conservation in a closed system when friction can be ignored, right? If you haven't, then here it is:
(KE+PE)start = (KE+ PE)end
KE refers to kinetic energy, PE to potential. It's basically stating that the total mechanical energy does not change if friction can be ignored. However, this is totally false in terms of happiness energy. Happiness energy does not have to stay the same before you go read a book and after, when you realize that book was really boring! So here's the real energy conservation law for that:
(T)start = (T)end
T refers to the energy of the thoughts, the most powerful of all in the world. Now it turns out we can't use this law to find out how much happiness energy they will all have, because we don't know how selfish or angry or sad her friends are at the beginning of the movie, only how happy they are at the end.
Okay, and now for this last part, which is not a law, just a point, is that happiness energy is actually measured in units of happiness energy. So total happiness energy would be in units of HE, not Joules like most forms of energy.
Actually solving the problem:
So let's move on. The truth is, you don't really need any complicated laws to solve this problem, just an idea of the laws above.
OPTION 1: Let's start with the first option, taking them to a movie, then to a party straightaway.
At the end of the movie, all three girls will gain happiness energy to result in 3(HE). Driving home, they lose a bit of happiness energy that transforms into the energy of hunger, etc., but since Jenny lives so close by to the theater, we deem that as insignificant. So at the end of the party, they also gain 3(HE).
Total (HE) = 3(HE) + 3(HE) = 6(HE).
So at the end of the party, they have 6(HE) of happiness energy left in them.
OPTION 2: Jenny takes them to the movie, then next week she has a party.
At the end of the movie, all three girls will have 3(HE) of energy, as said above. However, since there is a week in between, there is most likely energy loss, significant energy loss, because guess what, it's a school week. Throughout the week, they lose happiness energy and gain sadness energy, stress energy, etc. until going over to the party. By then, their 3(HE) must have reduced, due to quizzes, tests, and homework, and they cannot make it all up. At the end of the party, they gain 3(HE).
Total (HE) = less than 3(HE) + 3(HE) = less than 6(HE).
So since first answer is greater than the second, we can conclude option one of going out to a movie then a party right after would make her friends a a lot more happy.
And that's how to solve a problem using basic laws of physics! Here's your professor, signing out!
