Solve It with Fnet = m•a and Vectors - Directions


How it Works:

Using the Solve It with Fnet = m•a and Vectors Concept Builder is quite simple. There are three difficulty levels and each difficulty level involves the same task - analyzing a physical situation and determine force, mass, and acceleration values. When a value has been determined, it must be entered into the blank. You can do this by tapping on the blank. When you do, a numeric key pad opens; use the key pad to enter your answer. Once you do, you can close the number pad or click on a different blank to enter the numerical answer for that blank. You can check your answers any time by tapping on the Check Answers button. You will receive immediate feedback: correct answers will be marked with a green background and will no longer be editable. Incorrect answers will be marked with a red background and will have to be corrected. There is no limit on how many incorrect responses you can have. Once all answers are correct, you will be provided the next situation (there are two for each difficulty level) or returned to the Main Menu (if you have correctly analyzed both situations). Once you show success at a particular difficulty level, you will earn the trophy for that level.


Getting Help

You will notice that there is a Help Me button underneath the Progress Report. You should learn to use this feature of the program. It's how you can turn an exercise in answering questions into an exercise in learning. Tapping on the Help Me button will open a page with help that is specific to each question. Of course, the Help pages are only helpful if you read them. So take the time to read them. Each Help page contains four sections: a discussion of the The Basic Idea, a display of the Graph that you are trying to find a match for, a section titled "How to Think About This Situation", and a set of links to resources in our Tutorial section. You should pay attention to the section titled How to Think About This Situation. You will find what you need to know in the two or three paragraphs of this section. You will also become a better Physics student for doing that. That is, after all, the goal of such an activity as Solve It with Fnet = m•a and Vectors​.

Thanks for being patient with the Directions. Happy learning!
