Document Summary
Conceptual physics (11th edition) by paul g hewitt. No late homework is accepted, but she drops the 2 lowest homework grades. Meter (m: originally defined to be what was believed to be 1 ten-millionth the distance between the north pole and the equator, today is defined to be the distance traveled by light in. 1/299,792,458 seconds: based on the speed of light, a meter is a little longer than a yard, 1m = 1. 09 yd, a meter contains 100 cm. Pythagorean theorem: the square of each side (a,b) of a right triangle equals the square of the hypotenuse (c, c^2= a^2 + b^2, only works for right triangles. These are useful because the lengths of the sides are proportional (can be compared) Facts, theories, and law: fact- statement that experts agree on, hypothesis- educated guess, theories- synthesis of hypothesis and facts. Quiz: which of these often changes over time with further study: both facts and theories.
