## Shattering My Phone Screen

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

## Dog Sledding

To be competitive in the sport of dog sledding, speed it key. To achieve maximum speed, it is important to reduce the friction between the ground and the runners. Runners are the part of the sled that come in contact with the ground. They are sort of like skies that the basket of the sled is attached too. Normally, runners are made of metal, but racers add a rubber strip to reduce the coefficient of kinetic  friction between the runner and snow. Because the coefficient of kinetic friction is les

## The Physics of Eating Candy

While eating a Butterfinger, I pondered the question, "What is the physics of eating candy?" Through further investigation, I found that hard spherical  candies such as lemonheads decay at a constant rate. Andreas Windisch's, the man who conducted the experiment, found that the mass of candy decreased exponentially while the radius of the candy decreased at a consistently.  Windisch did note that the density of the candy does have to be equal throughout for it to decay at  a constant rate. This
