OBJECTIVE To gain understanding of the relationship between force, mass and acceleration. To measure the acceleration as a function of the mass and force INTRODUCTION Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is depend on two variables - the net force acting upon the object and the mass of the object. The acceleration of an object directly proportional to the magnitude of the net force acting upon the object, and inversely proportional to the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. This verbal statement can be expressed in equation form as follows: a = F net / m

Figure 2: The electronic weighing balance 3. The glider is placed in the starting position and affixed to the starter system with the magnet. The weight holder must be located directly adjacent to the light barrier’s wheel. Figure 3: The cart is on the plane with the weight holder 4. The glider is released and the recording of the measured values is started. The recording is started as soon as the weight holder touched the floor. 5. Step 3 and 4 are repeated by increasing the mass of the glider progressively by 20g increments. 6. By remaining the total mass constant, 2g is transferred from the glider to the weight holder. 7. Step 3 and 4 are repeated by increasing the mass of weight holder by 2g increment.

    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.
