What is the force exerted on your body in a crash related to?

• A. Your weight and the car's speed
• B. The weight of the car alone
• C. The speed of the car alone
• D. The number of passengers in the car

Answer: (A)

The force exerted on your body in a crash is related to both your weight and the speed of the vehicle. This is because, during a collision, the impact force depends not only on how heavy you are (your weight) but also on how quickly the vehicle is moving at the time of the crash (the car's speed). According to the principles of physics, the force involved in the crash is the result of both mass (which includes your weight) and acceleration, which in this case is represented by the speed of the car as it collides. Higher speeds lead to much greater forces, and a greater mass (your body weight) increases the overall impact felt. In contrast, focusing solely on the weight of the car, the speed of the car, or the number of passengers in the car does not give a complete picture of the forces at play during a crash. Each of these elements can affect the dynamics of a crash situation but do not reflect the direct relationship of force exerted on an individual, which combines both speed and weight.
