Module 3: Natural Forces Affecting the Driver Vocabulary: Please define six (6) of the following terms in your own words. Please do not just copy and paste the definition. 1. Gravity - The force that attracts a body toward the center of the earth, or toward any other physical body having mass. For most purposes Newton's laws of gravity apply, with minor modifications to take the general theory of relativity into account.
C. White lines (broken or solid) indicate what type of traffic flow: It indicate that traffic flows the same way and drivers are aloud to cross. 2. Observe and describe the different signs in YOUR city. Give specific examples of each (include color, shape, what the sign is for, etc.). A.
Centripetal Force- 9. Deceleration- Slowing down. 10. Force of impact- The speed of the object when it hit another object upon impact. Module 4 – Signs, Signals & Pavement Markings 1.
You absolutely must stop for what in a city type atmosphere if they are on the side of the road.__pedestrians _________________ 35. Draw a shared left turn lane. ______________________________. 36. These signs control the movement of traffic, usually are white on black and shaped in a vertical rectangle __regulatory signs_________________ 37.
Unit 4 Traffic Control Devices and Laws Definition and Purpose of Traffic Control Devices Worksheet 4.1 Signs, Signals and Pavement Markings Name Date 1. Traffic control devices are essentially signs, signals and markings that ________________________________________________ 2. A) On the line below each sign, identify the type of sign using the numbers on the right. 1 – REGULATORY Sign 2 – WARNING Sign 3 – GUIDE OR INFORMATIONAL Sign B) Complete the signs below by adding a message commonly seen on each sign along a road and give the main color of the sign in the space to the right of each sign. 3 ______ 2 _______ 2 ______ 2.
Solid White Line: marks right edge of roadway, do not cross 4. Broken White Line: separates traffic moving in same direction – crossing permitted 5. Solid Yellow Line: separates traffic moving in opposite direction – do not pass 6. Broken Yellow: separates traffic moving in opposite direction – passing permitted 7. What color are stop lines?
Have you forgotten the pedestrian traffic? Answer: No, k.) What types of pedestrian lights are used at the intersection? Pictograph walking man or hand in stop position? Countdown crossing timer? Answer: Both Page - 2 l.) What are the advantages or disadvantages of each type?
Refraction occurs when waves change speed when changing media. Diffraction occurs when waves bend around a barrier. 81. ANS: At the node, destructive interference takes place. At the crest (antinode), constructive interference takes place.
The vector function r(t) = t sin t, ___________ , t describes a spiral on the surface of a cone. B. For vector function r(t), unit tangent vector T(t) = b C. 10pts . r (t) dt is the __________________________ of a space curve r(t) from t = a t o t = b. a D. TRUE or FALSE: Curvature is negative when moving out of a curve. D. The normal plane for space curve C at a point is the plane containing unit vectors ______ and _______ E. F. TRUE or FALSE: B(t) does not need to be scaled since it is already a unit vector.
Move into the correct lane as you near the intersection. The correct lane for the right turn is the lane next to the right edge of the roadway. On a two-lane road with traffic in both directions, an approach for a left turn should be made from near the center line. voided by following some simple methods 4. Signal for at least the last 100 feet before you make your turn.
