major injury.
             By increasing the mass of an object you increase the inertia that the object has therefore increasing
             the amount of force due to an increase in acceleration. Many parents often allow their children to ride in the
             front seat of the car unbuckled. They say that if a collision occurs that they'll just reach over and hold the
             child back. If you really look at the physics behind their theory you will see that these parents are dead
             wrong. What is the force required to stop a 27 kg child travelling at 25 m/s? Momentum is equal to mass
             times velocity and impulse is equal to the change of momentum. Using the derived formula from the
             previous statement F * t = m * Vf - Vi we see that the force exerted on the
