1. Why are concepts in physics described with formulas? 2. Some wooden rulers do not start with 0 at the edge, but have it set in a few millimeters. How could this improve the accuracy of the ruler? 3. You find a micrometer (a tool used to measure objects to the nearest 0.01 mm) that has been badly bent. How would it compare to a new, highquality meterstick in terms of its precision? Its accuracy?
