This statement is best describing what consequence of your vehicle suddenly stopping? A. Force: the change your speed in a creates a large force on you and your car B. Momentum: The speed and mass of an object lead to greater dangers on the road C. Impulse: The change in momentum from moving to stop is what causes damage D. Speed: Going fast is dangerous and can result in death __

The best answer is **C. Impulse: The change in momentum from moving to stop is what causes damage.**<br /><br />Here's why:<br /><br />* **Impulse** is defined as the change in momentum. Since momentum is mass times velocity, a sudden stop represents a large change in momentum (going from some velocity to zero). This large change in momentum over a short period creates a large force, which is what causes damage in a collision.<br /><br />Let's look at why the other options are less accurate:<br /><br />* **A. Force:** While a large force *is* involved, the statement emphasizes the sudden change from motion to stationary. Force is a part of this, but impulse describes the overall effect of that force over the short time interval of the sudden stop.<br />* **B. Momentum:** While momentum plays a role, simply having momentum isn't the direct cause of damage. It's the *change* in momentum (the impulse) that matters in a collision. A parked car has zero momentum, but poses no immediate danger.<br />* **D. Speed:** Speed is a factor in the severity of a collision, but again, it's the rapid *change* in speed that causes the damage. The statement specifically addresses the sudden stop, which is about the change in speed, not just the speed itself.<br />
