Impulse and Materials: Which Material Is Most Likely to Provide the Best Protection for a Phone That Has Been Dropped? Introduction People throughout the United States use personal electronic devices. On any given day, a person might use a cell phone, smartwatch, laptop computer, or tablet in a number of different settings. Unfortunately, people often damage these devices by accidentally dropping them or knocking them off a table. Most consumers, however, do not want to replace any of these devices on a regular basis because they tend to be expensive. This is one reason why so many people use a case to protect their different personal electronic devices. Many different companies sell cases that are designed to prevent phones, tablets, or laptops from breaking when they are dropped or knocked off a table. When a person drops a cell phone, the force of gravity causes the phone to accelerate toward the ground at -9.8 m/s 2 . Any object with a velocity has momentum, and as an object accelerates during free fall, its momentum increases. Upon reaching the ground, the ground exerts an upward, normal force that causes the momentum of the object to change.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
