1. The adhesion, or grip, between the tires and the road surface is called:

A. Gravity
B. Inertia
C. Traction
D. Kinetic energy

2. How does gravity affect braking distance when driving downhill?

A. It lengthens braking distance
B. It has no effect on braking distance
C. It shortens braking distance
D. It decreases the vehicle's momentum

3. Hydroplaning can occur at speeds as low as _____ miles per hour.

A. 60
B. 50
C. 40
D. 35



Answer :

Final answer:

Traction ensures grip between tires and road, gravity impacts braking downhill distance, hydroplaning occurs at low speeds.


Explanation:

Traction is the adhesion or grip between the tires and the road surface. This grip is essential for maintaining control while driving.

When driving downhill, gravity lengthens the braking distance as it adds to the force pulling the vehicle down the slope, requiring more effort to stop.

Hydroplaning can occur at speeds as low as 35 miles per hour when water accumulates between the tires and the road, causing loss of traction.
