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.


  1. How is the dependence of acceleration on force and mass? Is it equal? how about situations where friction is present?

  2. It was very good overall. You could elaborate more on the relationship between acceleration and mass but other than that the answers were clear and well written. This is Paxton by the way.

  3. The greater the mass the faster it will speed up? can you explain what you mean by that, in what context does this happen. How is this related to N2L. Also,isn't mass and acceleration inversely proportional? please clarify your posting.
    You still have not explained situations with friction.
