Conductors and insulator


In golf, clubs are used to smash the golf ball from place to place. In this photo, I have a club in my hands, which can show to be both a conductor and an insulator. It is tough to see the insulator part of the club in this picture. If you can find the part of the club where my hands are holding, behind my head, it is called the grip. The grip is made of rubber which is an insulator as it does not allow electrons to move throughout the club. The conductor is the metal part of the club, which includes the club head, which is the round shaped part of the club, as well as the shaft which connects the grip to the club head. These are conductors as they are both made of metal, which allows electrons to move throughout the club allowing it to heat up. It is cool to think that one object, such as a golf club, has both an insulator and a conductor.

David Fink Physics Journal #1

In this image, my brother and I are standing in Oregon on a golf course. I was golfing that day and my mom took a picture on the third hole showing that the wind moves the flag. The golf course was very windy which is amazing the picture came out with the flag, as sometimes the flag will be moving so fast it would be too blury to see the details. As wind blows, different types of waves. But in this image, transverse waves are blowing the flag making it wave. The reason it is called transverse is because the flag is blowing in the same direction the wind is blowing. This is how it relates to physics, as the flag clearly shows that it is moving with the side to side or left to right wind. If the flag was waving up and down, the term of the waves would be longitudinal.
