About a month ago I shattered the screen on my phone. Fortunately however, this meant that I could get a new phone. From this experience, I learned why my phone shattered compared to previous times it dropped. I realized that the impulse it experienced was much greater compared to the times I dropped it on carpet. The equation for impulse is Impulse= force x Δtime. Because the force of mg was constant throughout its fall (neglecting air resistance), that meant that Δtime was the reason for the different impulses. When my phone fell on carpet, the time to stop the fall was slower than the time it took when my phone fell on tile floor.
