In unit 6 the main focus is on Newton's second law of motion. Newton's second law of motion states that the acceleration of an object is directly proportional to the new force of an object while the acceleration of an object is inversely proportional to an objects mass. In the picture I am pushing my backpack. This is an example of Newton's second law of motion because there are forces occurring in the situation. I can draw a free body diagram for this motion. Fnet = m*a or N - m*g = m*a, is the equation that represents the second law. In this situation of me pushing my backpack, I would need to weigh my backpack to find the mass. Then I would just need to calculate the acceleration I am pushing at and then I can plug and chug to find N (force).
