Any more August Bell work. Leave it on your desk number please Any more August Bell work? Leave it on your desk number please. Bell Work: Vectors Graphically When you scale a drawing you change its ( shape / size ). The answer to a vector problem is called the ( components / resultant ). If 10 meters is scaled to = 1 cm, how long would you draw a 140 m vector? If your resultant was 17 cm long, how many meters would that represent? (same scale as 3.)

Practice Test Correction (Longhorn Time next week) To earn back half credit. . . . . Choose the correct answer. Back up your answer choice with a piece of information about why the new answer is correct or why the old answer is wrong.

Practice Test Correction The unit for displacement is m/s2 m/s original wrong answer m s On your paper: C m/s2 measures acceleration OR 1. C displacement is how far, just like distance. Both have units of meters.

Practice Test Correction 2. The resultant is drawn from ______. End to beginning Beginning to end original wrong answer Left to right Top to bottom On your paper: 2. B resultant points the same way that the components point OR 2. B to show where your going a vector has to point away from the start point

Practice Test Correction 3. Which is a scalar? force momentum original wrong answer weight temperature On your paper: 3. D temperature does not have a direction OR 3. D force, momentum, and weight all have directions making them vectors

Today . . . Finish part A of vector practice Connect angle measurements to cardinal directions.
