If you are a young physicist, or anyone looking to understand the physical world around them, one of the first steps is the difference between vector and scalar quantities. Reviewed in this app are over 25 common vector and scalar quantities, such as distance, displacement, speed, velocity, momentum, force, time, etc. which are presented in flash card, tap review, and list format. First review the list, and take a step further by reinforcing that knowledge by tapping each quantity to see the answer. Finally, drive the knowledge home with a quick flash card review anywhere you have a spare moment. Good luck!
