Two cars are travelling down a highway at 100 km/h in opposite directions. Both drivers are tired from driving all day and cross over the yellow line and hit head on. Crash! The driver of car A has remained inside the car and has broken ribs due to hitting the steering wheel. The driver of car B however is on the hood of car A and is pronounced dead at the scene, cause of death, a severe case of disobeying the laws of physics. Although both cars were heading at the same velocity one driver ended up dead while another survived. This seems like a complicated and hard thing to explain and to the untrained person it may seem that driver A just had plain luck on his side however this is untrue. Using the knowledge of basic physics I hope to explain why the outcome for each driver was different and could have been avoided. Sir Isaac Newton was the first man to explain what happens in a collision even before automobiles were invented. He proposed the idea that an object in motion will continue in motion with the same speed and direction unless acted upon by an outside,
