Accepted Answer

### Question 10
# Brief Explanations:
- Traction refers to the grip of tires on the road surface, so a (Traction) matches B.
- Gravity is the force that pulls objects (including vehicles) downhill, so b (Gravity) matches A.
- Inertia is the tendency of an object to remain in its state of motion (or rest) unless acted upon by an external force, so c (Inertia) matches C.
# Answer:
a. Traction - B. Tire grip on the road surface
b. Gravity - A. Force pulling vehicles downhill
c. Inertia - C. Tendency of objects to remain in motion unless acted on

### Question 11
# Brief Explanations:
Factors affecting traction include road surface conditions (e.g., wet, icy, dry) and tire conditions (e.g., tread depth, tire pressure). Another factor could be vehicle weight distribution, but road surface and tire conditions are common examples.
# Answer:
a. Road surface conditions (e.g., wet, icy)
b. Tire conditions (e.g., tread depth, pressure)

### Question 12
# Brief Explanations:
Drivers can maximize traction by maintaining proper tire pressure, ensuring good tire tread depth, driving at appropriate speeds for road conditions, and avoiding sudden acceleration/braking/steering.
# Answer:
Drivers can maximize traction by maintaining proper tire pressure, ensuring adequate tire tread depth, driving at speeds suitable for road conditions (e.g., slower on wet/icy roads), and avoiding abrupt acceleration, braking, or steering maneuvers.

### Question 13
# Brief Explanations:
Stopping distance is related to the square of speed (from the physics of motion: $ d \propto v^2 $ for braking, where $ d $ is stopping distance and $ v $ is speed). If speed doubles ($ v_2 = 2v_1 $), stopping distance becomes $ (2)^2 = 4 $ times the original (assuming constant braking force and road conditions).
# Answer:
When a vehicle’s speed doubles, the stopping distance (including reaction and braking distance) becomes approximately four times the original stopping distance (since stopping distance is proportional to the square of speed, $ d \propto v^2 $).

### Question 14
# Brief Explanations:
Improper steering or braking can cause loss of traction (skidding), loss of vehicle control (e.g., oversteering/understeering), increased stopping distance, or vehicle rollover (in extreme cases). Forces like inertia and gravity can exacerbate these issues, leading to collisions or loss of control.
# Answer:
During improper steering or braking, a vehicle may lose traction (skid), lose directional control (e.g., oversteer/understeer), experience increased stopping distance (if braking is improper), or even roll over (in severe cases). This can result in collisions with other vehicles, objects, or loss of control on the road.

### Question 15
# Brief Explanations:
More than 50% of fatalities occur in single - vehicle crashes (e.g., hitting a tree, rolling over, crashing off - road), as per traffic safety statistics. Multi - vehicle crashes and low - speed collisions have lower fatality percentages in comparison for this statistic.
# Answer:
Single - vehicle crashes (the checkbox next to "Single - vehicle crashes" should be selected)
