Gravity & Circular Motion Review The radius of the earth is about 6400 km. What would be the earth's gravitational attraction on 75 kg astronaut in an orbit 6400 km above the earth's surface. The mass of Mars is about 6.6 x 1023 kg, and the acceleration due to gravity is 3.7 m/s2. What is the radius of Mars? The earth's radius is 6400 km. A 25 kg mass is taken 201 km above the earth's surface. What is the object's mass at the height? What is the weight of the object at this height? What is the acceleration due to gravity at this height? The radius of a planet is 3400 km. If an object weighs 550 N at the surface of the planet, what is its weight 12 km above the surface? 210 km above the surface?

Quantitative properties - associated with numbers Units must always be specified Scientific measurements use the metric system SI Units Seven base units are used by SI Prefixes are used to modify powers of 10 of these units Length and Mass Mass - the measure of the amount of material in an object Temperature - a measure of hotness and coldness (physical property) Heat flows spontaneously from the hotter object to the colder one Celsius scale - created considering water's boiling and freezing points Kelvin scale - created so that 0K is the lowest possible attainable zero (absolute zero) The Kelvin and Celsius scales use the same-sized units around a different zero Derived SI Units - obtained by the multiplication or division of one or more base units

01.03 Units and Graphs Essential Questions After completing this lesson, you will be able to answer the following questions: How do you use units and convert them to understand and solve problems? How are units of measurement chosen and interpreted in formulas? How do you choose and interpret scales on graphs and data displays? Main Idea (page #) DEFINITION OR SUMMARY EXAMPLE Choosing Units of Measure (pg. 2) A good rule of thumb to use is that when measuring something small, use a _____ unit of measure. When measuring something large, use a _____ unit of measure. To measure the length of a smartphone, use ____________. To measure the weight of an elephant, use _____. TIP: Make sure that the unit is not too large or too small to represent the measurement.

If the three members of the crew are decided at random, what is the probability that Chase is selected for lighting, Jaden is selected for props, and Emelina for spotlighting? What is the probability that a license plate using the letters C, F, and F and numbers 3, 3, 3, and 1 will be CFF3133? Alfonso and Colin each bought one raffle ticket at the state fair. If 50 tickets were randomly sold, what is the probability that Alfonso got ticket 14 and Colin got ticket 23?

Stats: Modeling the World Chapter 19 Confidence Intervals for Proportions Making an educated guess? Rarely do we actually know information about our population. Usually we: - take a sample - find a sample statistic - make a guess about the true parameter value Our guess will be a bit off, this is the idea of a confidence interval. The sample proportion ? Recall from Chapter 18 that the sampling distribution model of ? is centered at p, with standard deviation . Since we don?t know p, we can?t find the true standard deviation of the sampling distribution model, so we need to find the standard error: The Empirical Rule Revisited? By the 68-95-99.7% Rule, we know - about 68% of all samples will have ? ?s within 1 SE of p

He believes the true proportion of voters with a certain opinion is within 4% of his estimate, with some degree of confidence, perhaps 95% confidence. 2. Margin of error. He believes the true percentage of children who are exposed to lead-base paint is within 3% of his estimate, with some degree of confidence, perhaps 95% confidence. 3. Conditions. a) Population ? all cars; sample ? 134 cars actually stopped at the checkpoint; p ? proportion of all cars with safety problems; p? ? proportion of cars in the sample that actually have safety problems (10.4%). Plausible Independence condition: There is no reason to believe that the safety problems
