The force of an impact during a wreck is directly affected by what?

The force of an impact during a wreck is directly affected by the speed of the car(s) involved in the crash due to the principles of physics, particularly Newton's second law of motion. This law states that force is equal to mass times acceleration (F = ma). In the context of a car accident, when the speed of a vehicle increases, the kinetic energy at the moment of impact also increases. Kinetic energy is calculated using the formula KE = 1/2 mv², where m is mass and v is velocity. As the velocity increases, the kinetic energy increases exponentially, resulting in a greater force being exerted during a collision. Consequently, higher speeds lead to more severe impacts, making speed a critical factor in the force experienced during a crash.
