PHY 121 Midterm: PHY 121 - Term Test 1
Document Summary
The different realms of physics, and their applications in both natural and technological systems. The angle in radians is defined as the ratio of the subtended arc length . To convert degrees to radians and vice versa, simply multiply the angle to . A method used to approach mathematical calculations consisting of variables and symbols. Both sides (left and right) must have the same dimensions/units. Notice that both left and right sides of the equation has the same units. The prefixes used in this course (refer to table 1. 1 on page 4 of the textbook): Sometimes, units are given in different measurements and it"s important to know how to convert from one unit to another. How to express and manipulate numbers in physics calculations. A reasonable sized-number that is multiplied by a power of 10. General rule for adding and subtracting numbers in scientific notation. In order for that to occur, the numbers must be multiplied by the same exponent.
