If you slam your finger in a car door how can you thank Coulomb's Law for the fact your finger wasn't chopped off?
Without Coulomb's law, you would not exist.
Come on! That's not the answer. There is something there that I am not getting why it would matter.
Coulomb's Law is actually not directly related to why your finger wouldn't get chopped off when you slam it in a car door. Coulomb's Law deals with the electrostatic force between charged objects, while the situation you described involves mechanical force.
However, we can explore some principles of physics that can help explain the preservation of your finger. One fundamental physics concept that applies here is Newton's third law of motion, which states that for every action, there is an equal and opposite reaction.
When you slam your finger in a car door, a large force is applied to your finger due to the rapid closing of the door. In response to this force, your finger exerts an equal and opposite force on the car door. This force acts to counteract the door's motion and prevents it from closing completely and potentially severing your finger.
Another factor that contributes to the preservation of your finger is the compressibility and elasticity of the tissues in your finger. When the door makes contact with your finger, the tissues can absorb some of the force and compress, acting as a cushion and reducing the severity of the impact.
It is important to note that while these principles explain why your finger is not usually chopped off in such situations, the extent of the injury may still vary depending on the specific circumstances, force applied, and other factors. In any case, if you find yourself in this unfortunate situation, seeking immediate medical attention is crucial.
