Eli5: Why does time matter in physics?

1.02K views

If I drive my car through a corner slowly I’ll be fine. If I go fast, the car will skid off the road. All the materials are the same, the execution is the same. The only difference is over what amount of time this happens? The example is not important, the same goes for pretty much anything. Filling a bottle, ripping a sheet of paper..

I understand this from a intuitive perspective, but I wonder if someone can explain why time matters in physics in a simple way. What is the fundamental difference between doing something fast vs. slow.

I’m sure this is a silly question if you know some thermal dynamics or special relativity, but remember, I’m only 5!

The difference in those situations is not the time itself, but how quickly you are doing those things. Speed CAN and WILL affect the outcomes of situations (for example, the car must slow down much more than it has to if it is moving at a slower velocity) such as the ones you’ve listed. The time the action takes is because of the speed in which it is happening, not the other way around.
