Objective: To use the air track to experimentally investigate Newton’s second law and to use spreadsheet-generated linear regression to analyze the data. Apparatus: Airtrack, glider assembly, pulley and cord, appropriate clamps and supports, set of slotted masses, four Pasco infrared photogates, and the Pasco 750 Interface System. Theory: Newton’s second law, namely F = ma. It has been one of the cornerstones of classical physics since it was first formulated. The idea that force changes motion rather than maintains it was at odds both with Greek thought and “common sense”. The reason for this is the friction had clouded the thinking of researchers prior to Newton. In the case of friction, a force is needed to maintain motion. But Newton was able to abstractly consider the case of no friction.

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
