Physics is involved in our livings

Do many people know that science especially physics is involved in our livings? Probably, most of us don¡¯t quite sure about that. However there are lots of physical involvements in our livings. One of the greatest examples that express physics involvement is the roller coaster. The roller coaster has some concepts of physics which are acceleration, inertia and energy. Firstly, there are acceleration and deceleration in the roller coaster. As seeing the diagram, in …

…But the roller coaster has wheel so it may decrease friction. As mentioned above, there are lots of physical concepts in the roller coaster such as acceleration, inertia and energy. All those act exactly same as we learn in the class. Actually, there are lots of physical concepts in our living. If people who learn physics and like to study it, it had better go the Playland and experience what actually happen on the rides.
