Document Summary

Multiplication or division: the number of significance is equal to the number of significant figure in the least accurately known quantity. Addition and subtraction: the number of decimal places after addition or subtraction is equal to the smallest number of decimal places in any of the individual terms. Problem solving in physics; here are some guidelines: read the problem carefully, sketch the system, visualize the physical process, strategize 5. Identify appropriate equations: solve the equations, check your answer, explore limits and special cases. The study of how objects move, how they respond to external forces, and how other factors, such as size, mass and mass distribution, affect their motion. This time we treat all physical objects as point like particles. Coordinate system: defines an origin, a positive direction (orientation) and a unit of length, uses one or more numbers to uniquely determine the position of a point. Earth is three dimensional (length, width, and height)
