Let's cut to the chase: Life is full of decisions, especially as a senior in high school. Over the years I have noticed that many people have a difficult time making decisions, so I have decided that I am going to release my decision-making secret, the reason why I can so easily make decisions: I use math.
Making decisions is like momentum (p= mv) , two opposing forces collide, changing the directions of the objects. To make things simple, let's refer to only two balls (aka choices). Each ball has a different mass, which is the equivilancy of importance for you. For example, a math test would probably have a higher mass than going to the movies to see Side Effects (which comes out February 1st ^-^ ). In most cases, the objects/ choices are travelling at different velocities, also known as the personal preference velocity. Using the scenario above, going to see the movie would have a high velocity than studying for that upcoming test. With hat information, there is only one thing left to do: LETS GET READY TO RUMBLE!!!
To find which decision is best, assign one choice as a negative and the other as a postive (it doesn't matter who gets one sign). then, using conservation of momentum, figure out which direxction the objects will go after the collision (you need to use a sticky collision). To show how it would work, I am going to plug in numbers for myself:
mTest= 5 (for economics)
vTest= 7 (since I already have a 88 in the class which is low for me)
mTestvTest + mMoviesvMovies =(mTest + mMovies )v'
5(7) + 2(-10)= (5 +2) v'
35- 20= 7v'
Thus, the best choice in this situation would be to stay home and study for the test; so I will have to wait to see Side Effects after I get an A on the test.
Well, now you know my secret to successful decisions!
(Warning: with three or more decisions this equation does work but instead of putting it into a collsion, simply compare the momentum of each choice (signs will not matter, so they can all be positive). Which ever momentum is highest is the best choice. And yes, I actually do something like this in my head everytime I have a difficult decision to make. What you think I leave it up to feelings? Physics is the answer to everything!)
