And physics is a good subject, don't get me wrong. I'm doing well in it and I really like my teacher.
But I'm stuck.
"How much work (change in kinetic energy) was done to bring Car 2 to a stop?"
And right about now Im thinking...
When am I going to need to know how to find how much work is being done or how much KE something has or how much momentum it has? I dont want to be a physicist or a rocket scientist, i just want to be a photographer and a horse trainer and maybe some medical person. Physics is not involved in any of those...
So this is just useless information...

I hate to be "that guy", but all of those involve physics.
Photography is mostly physics. There's a little chemistry, but for practical purposes (especially in digital media), physics is more important. How light reacts to a small opening, how it reflects. These are the things a photographer needs to know to do the craft portion of her art.
Don't you think an appreciation of how the mass and speed of a moving object affects how hard it is to stop it is useful for a horse trainer?
Think about most of the "interesting" medical tests that you've ever undergone. X-rays, MRIs, CAT Scans, ...
However, I definitely understand how inane most test questions are, for all subjects.
:)
Without physics, you would not be able to take pictures. Cameras (from pin-hole, single-lens reflex to digital) operate on physics principles.
Physics not involved in horse training? Seems to me that riding a horse and falling off a horse both involve Newton’s Laws of Motion! Maybe you will find physics more interesting if you can relate it to something you love. Check out this website:

How is physics involved in medicine? In more ways then you could ever imagine! Have you ever heard of x-rays? Ultrasounds? MRIs? Chemotherapy? All of these involve physics!
Hospitals, clinics, and major medical centers use radiation sources, including x-ray machines, particle accelerators, and many types of radioactive materials. Radiology, nuclear medicine, and radiation therapy departments are found in almost every modern hospital today. Each of these departments utilizes radiation sources, and medical health physicists are needed to ensure proper and safe working conditions for both patients and medical staff.
As a medical transcriptionist I need to know physics to transcribe x-ray reports and operative notes. Laser radiation and radiofrequency ablation are frequently used in medical procedures. I'm just one of those "medical persons" on the clerical side of healthcare. I won't even go into how much physics you need to know to be a nurse, doctor, technologist, surgeon, veterinarian, etc.
Okay, I already know physics is involved in every single thing, even sitting in this chair. I get that already.
But I dont NEED to know all the formula's and stuff. While it's very interesting to learn how this stuff works, its not going to affect my equine, photography or possibly medical career if I dont know that w=fd
I never had physics in school. Most of my physics education came from my ballet mistress (who was really really really good at helping dancers achieve their utmost by explaining anatomy and physics). My physics ignorance hit me in the forehead when I had trouble helping my fourth grader with her home school experiments this year. Now I wish I'd learned it when I had a teacher rather than when I am the teacher.
Pretty arrogant attitude for a student .... isn't it?
huh? x_x
Scott, yeah it certainly is. :-)
Emily, you may not need all the formulas, but to understand that there is practical application behind all those formulas is important.
Admitting ignorance is the first step. :-p
I'm with you Emily....who needs it?
