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
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
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
About a week ago, our AP Physics C class was presented with the challenge of calculating the landing spot of a projectile. Unfortunately, we missed the mark due to communication issues and a time constraint. Using measurements from the first launch, the initial velocity was found to be 4.68 m/s( I calculated the x and y components of the projectile then found the resultant). Next, I used the measurements from new height of 1.035 m at an angle of -4 degrees to find the new y component. This y c
The first week of physics was very interesting and I really enjoy the freedom of being able to work at my own pace. Hopefully it will not lead to procrastination. I decided to take physics because it is a extremely challenging, yet interesting. It allows me to see the world in ways I had never seen it before. I want to learn more in depth about concepts and fully understand concepts that I was confused about last year. I am most excited for the labs we will do. Out of any science class, physics
