Next , think about the most exciting modern technologies that you have heard about in the news , such as trains that levitate above tracks , `` invisibility cloaks '' that bend light around them , and microscopic robots that fight cancer cells in our bodies . All of these groundbreaking advancements , commonplace or unbelievable , rely on the principles of physics . Aside from playing a significant role in technology , professionals such as engineers , pilots , physicians , physical therapists , electricians , and computer programmers apply physics concepts in their daily work . For example , a pilot must understand how wind forces affect a flight path and a physical therapist must understand how the muscles in the body experience forces as they move and bend . As you will learn in this text , physics principles are propelling new , exciting technologies , and these principles are applied in a wide range of careers .
