Final answer:
The answer to the student's question is to slow down when approaching turns in the road due to inertia, which tends to keep the car moving in a straight line according to Newton's first law of motion.
Step-by-step explanation:
The student's question refers to the principle of inertia and how it affects a car's motion when turning. To fill in the blanks: You should slow down as you approach turns in the road because the force of inertia will try to keep the car moving in a straight line. Inertia is the tendency of an object to resist changes in its state of motion. This concept is rooted in Newton's first law of motion.
When a car approaches a turn, inertia wants to keep the car moving in a direct line at a constant velocity. Hence, when turning, you must slow down to overcome this natural tendency, permitting the car to follow the curve of the road. As you make this turn at a slower speed, the inward force that allows you to turn without sliding outward (centripetal force) does not have to be as great, making it safer and easier to navigate the turn.
