This is what I learned about Newton's Second Law. I learned it says that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object. The direction of the force is the same as the acceleration.
What I have found difficult about what I have studied is solving problems with the coefficient of friction. At first, the problem seemed unsolvable but if you kept working the it, the answer would find its way to you.
My problem-solving skills are fine for the time being. After I missed a few classes, the material seemed hard, but it is easy now. I understand how to draw FBD's and after a miscalculation on our recent quiz, I realize that if the object is in Newtons, it DOES NOT have to be multiplied by 9.8. Other than that, I fell like I am a good problem solver.
