Lesson 8: Evaluating Vehicle Design:
Looking at Friction
 Question: How does friction affect the motion of your vehicle?
 Hypothesis:
 Plan/ Observations: Record Sheet 8-A (3 sheets)
 Card One:
 Card Two:
 Card Three:
 Conclusion/Reflection: Friction is the force that resists
movement between two objects that are touching. It slows down
movement.

Lesson 10: Testing the Effects of Air
Resistance on a Vehicle’s Motion
 Question: What is air resistance? How does air resistance affect the
motion of a vehicle with a sail?
 Hypothesis:
 Plan/ Observations: Chart
Lesson 10 continued
 Conclusion/Reflection: Air resistance is the force of
friction on a vehicle as it moves through the air. It
opposes a vehicle’s motion and slows it down.
Engineers refer to air resistance as drag. Designs that
minimize drag are known as aerodynamic (able to
move through the air with as little air resistance as
possible). For example, many automobile shapes are
curved without sharp corners.

Conclusion/Reflection: Propellers create a force that
moves airplanes and boats forward. Even when an
airplane is on the ground, the force from the spinning
propellers enables it to taxi on and off the runway.

Lesson 12: Analyzing the Motion and Design
of a Propeller-Driven Vehicle
Question: How will modifying the propeller driven vehicle
affect its performance?

Lesson 13: Looking at Cost
Question: How can you modify your propeller-driven vehicle to make it
more cost-effective?
Hypothesis:
Plan/ Observations: Record Sheet 13-A
Conclusion/Reflection: Cost-effective is the ability to produce the best
results for the least amount of money.
You can reduce vehicle cost by:
-taking off the big pieces that cost a lot
-replacing larger wheels with small wheels
-taking off fancy pieces that are just for looks
-reducing the number of pieces.

Newton’s Laws of Motion
Three laws that describe how objects move in
relation to the forces acting on them.
1. An object in motion tends to remain in motion, and
an object at rest tends to remain at rest (Inertia).
2. To move a mass, you have to have force. Force
equals mass times acceleration.
3. Action/ Reaction: For every action, there’s an equal
and opposite reaction.
