factors can play into an accident. Road condition‚ mechanical failure‚ driver error‚ or simply an ’act of God’? Despite the countless reasons for a car accident‚ one factor is always present‚ no matter what the case: physics. Every accident that has ever occurred has involved physics. Using references found in the class text‚ in science journals‚ and on the Internet‚ I will prove this to you. Take‚ for example‚ two cars traveling in opposite directions at 100km/h. One of the drivers dozes off and

before stopping. (D) The 2 kg mass travels greater than twice as far. (E) None of the above The correct answer is (B) The 2-kg mass travels twice as far as the 4 kg mass before stopping. To calculate the distance the object will slide one can use the work-energy theorem that states that the work done to a system is equal to the system’s change in energy. Here‚ the object starts with kinetic energy [KE = (mv^2)/2] and friction brings it to rest by doing an equivalent amount of work. Work

Good manners cost nothing‚ but they bring about handsome rewards. When someone says "please" or "thank you" he actually finds himself in the midst of cheerful crowd. When someone is polite and soft spoken‚ he gets over many difficult situations in life. Good manners and courtesies are not‚ however‚ born with us. They
