Newton's Second Law

In Newton's Second Law I learned that acceleration depends on the sum of all forces (net force) and the mass of the objects. The greater the mass is the quicker it will speed up and reach the ground. The most difficult part in completely the problems is making sure that your free body diagram is complete. Once you have a good FBD solving the problem is very simple. Overall my problem solving skills have improved because I take more time to make sure that the FBD is complete and correctly done.
