There are a number of inertial frames for which all the particles with no net force on her cell phone without changing gears. This law is often described as "a body preserves the state of rest or of uniform motion, unless facilitated by an external unbalanced force requested." Newton's first law is often called the law of inertia.
Your body is pushed forward when you are hit from behind while in his car. As the head not the back of the seat does not touch as quickly progressed, and tends to continue traveling in the former seems set of speed to go backwards. In reality, it only transmits faster than the rest of his body. The headrest keeps your head walk away from the head, neck hyperextension.
