People sometimes engage in activities and are unaware that such activity involves physics. Physics is all around. For instance‚ you may go to Six Flags and do not analyze how physics helps the machines you ride in operate. Have you ever asked yourself how a roller coaster works? Would roller coasters safely run without the knowledge that physics offers us? The answer is no. Roller coasters are driven by physics; it mobilizes and gives its riders amusement through forces such as inertia‚ gravitation

amusement park is not an amusement park if it does not contain a roller coaster. What makes these roller coasters so fun that every amuse parks has one. A lot of people would say it is their extreme high speeds that makes it very exciting. That is a valid answer‚ but it is the wrong answer. The speed has nothing to do with the excitement. It is more than likely that most people travel faster on their ride along the highway on the way to the amusement park than they would in a roller coaster. Basically

5 of the biggest unsolved mysteries in physics The mysteries of the universe are as vast and wide as existence itself. Throughout history‚ mankind has searched and struggled to find the answers tucked away inside the universe and everything we see around us. As Deep Thought said in the Hitchhiker’s Guide to the Galaxy‚ "I think the problem‚ to be quite honest with you‚ is that you’ve never actually known what the question is." True‚ we have yet to come up with the answers to life‚ the universe
