Which of the following statements about collision impact forces is true?

When considering the relationship between speed and the forces involved in a collision, the correct statement highlights that if you double your speed, the energy dissipated in a crash increases by a factor of four. This principle is grounded in physics, specifically in the kinetic energy formula, which states that kinetic energy is equal to one-half of mass times velocity squared (KE = ½ mv²).

As velocity increases, the kinetic energy increases exponentially. Therefore, if you double the speed, the calculation of energy would look like this: (2v)² = 4v². This means the energy is quadrupled. Understanding this relationship is crucial for drivers and road safety advocates, as it illustrates the significant impact that speed can have on the severity of a collision. Even a modest increase in speed can greatly enhance the risk and consequences of a crash.
