## Physical Therapy

As I was desperately researching different topics to write about, I came across an article describing how physical therapy relates to physics. As a former physical therapy patient, I know the painful and difficult tasks required to heal. According to the article, Torque, electromagnetic force, and gravitational force are relevant to physical therapy. Also, physics itself is obviously applicable to the movement of the body through all the forces of nature. Torque applies to physical therapy as th

## Physics applies to health

I've always been curious to if physics applied to health and the importance of it. So, while researching this I found that physics does apply to health in many different ways. For example, if someone breaks their bones, doctors use x-rays which are a product of physics. Another medical use of physics is when a woman is given an ultrasound, this is a form of physics because you're watching the process of physics in action. Also one of physics other creations, the defibrillator, can be the differe

## Roller Coasters

Over the summer I worked at Seabreeze Amusement Park and I was a ride operator. My job is to operate rides, keep children safe, and provide fun. As a ride operator I am curious to know how physics can apply to roller coasters. According to a website I researched, physics applies to roller coasters in a variety of ways. For example, neglecting friction and air resistance a roller coaster will experience two types of forces, the force of gravity and the normal force. The normal force is directed

## Physics applied to driving

As a new driver I was very curious to learn how driving can be applied to physics. So, I researched many websites to get knowledge on this subject. According to one website, Newton's third law applies to driving. For people who don't know what Newton's Third Law is, it means that in every interaction there is a pair of forces acting on the two interacting objects. Newton's third law applies to driving because when you drive the action force is pushing against the road and the reaction is the roa

## physics in dance

Hi Everyone, Ever since I was three I have been dancing and physics applies to dancing in many ways. For example, in order for dancers to stay balanced during dances, the dancers center of gravity must remain directly above the area of contact with the floor, otherwise the dancer would tip over. Also with the decrease in inertia and the increase in velocity I am able to turn or spin faster. In addition, if I was to do a turn in the air the only force that would be acting on is gravity. These
