They increase the time taken to change the momentum of the driver and passengers in a crash, which reduces the force involved. Force and Acceleration. Force = change in momentum ÷ time = 300 ÷ 5 = 60 N To change the momentum of an object you can apply a small force over a long time, or a larger force over a shorter time. This counteracting force is called the normal force, and is represented by FN, or N. The unit for the normal force is 'N' (Newton). Here we can calculate Weight, Mass, Gravity.

Think also about this: If you applied a force equivalent to 100 km/h times the mass in the opposite direction of vehicle 1, that would actually make vehicle 1 change direction and go backwards at 50 km/h after the collision. 1 g is the average gravitational acceleration on Earth, the average force, which affects a resting person at sea level. During an impact, the energy of a moving object is converted into work, and force plays an important role. Normal force is the perpendicular force that the surface exerts on an object. Input all parameters into the AASHTO equation: s = (0.278 * t * v) + v² / (254 * (f + G)) s = (0.278 * 1.5 * 120) + 120² / (254 * (0.27 + 0)) s = 50 + 14400 / 68.6. s = 50 + 210. s = 260 .
