Module 04 Reflection Journal (Module 3 and 4)

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. Inertia- Newton’s law of inertia it says that an object at rest tends to stay at rest and an object in motion tends to stay in motion
2. Potential Energy- Potential energy is the energy that matter has because of the way it’s positioned.
3. Kinetic Energy- Kinetic energy is the energy developed by an object when it is in motion
4. Friction- Friction is the resistance of movement between two objects
5. Centrifugal Force- When a car moves along a curved path it’s velocity is changing. Centrifugal force is the that causes this. It directly means center seeking force.
6. Centripetal Force- This is a force that pulls from the center of the car when in a circular motion. It’s the opposite of centrifugal force and does increase with acceleration.

Module 4: Signs, Signals & Pavement Markings
1. Explain the purpose of the following
A. The difference between solid and broken lines is:
The main differences between solid and broken lines are that when the lines are solid you can not change to a different lane but when the lines are broken you may change to a different lane.
B. Yellow lines (broken or solid) indicate what type of traffic flow:
Yellow line indicate that the road is used for two-way traffic
C. White lines (broken or solid) indicate what type of traffic flow:
White lines indicate that the traffic is flowing in your direction

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. A regulatory sign:
A regulatory sign would be a speed limit sign telling you how fast you can drive on the road.
B. A motorist services sign:
A motorist sign would be blue it could also be for a handicap parking spot.
C. A recreational sign
A Recreational sign are brown and rectangular. They nor,ally tell you about historical and cultural interest. They also will say where the federal and state parks are.
D. A sign that you know what it means because of its shape:
You know If you see a sign the shape of a triangle that it’s a yield sign
*If each of the above signs do not appear in your town then describe any 3 different types you see in your community.

3. Explain 3 interesting or important facts from Module 3 and 4.
A. I enjoyed learning about all the different road signs and what all the different shapes and colors mean.
B. I enjoyed learning about Newton’s Law of Inertia how when an object at rest tends to stay at rest and an object in motion tends to stay in motion
C. I enjoyed learning about the Centrifugal and Centripetal force and how they are exact opposites.
