Question

When does a curve become a turn: none of the answers, when it is a right angle, when it can be safely navigated at a speed less than 35 mph, when you must stop first

Answer 1

A curve becomes a turn when it cannot be safely navigated at the ideal speed, when the friction between the tire and the road is not enough, or when it is a banked curve.

Step-by-step explanation:

In physics, a curve becomes a turn when the vehicle must change its direction. There are several factors that determine when a curve becomes a turn:

1. Ideal speed: A curve becomes a turn when it cannot be safely navigated at the ideal speed. The ideal speed is the maximum safe speed at which a vehicle can turn on a curve without the aid of friction between the tire and the road.
2. Friction: A curve becomes a turn when the friction between the tire and the road is not enough to safely navigate the curve at a certain speed. Friction provides the necessary centripetal force for the vehicle to turn.
3. Banked curves: In some cases, a curve becomes a turn when it is a banked curve. Banked curves have a sloping road surface that helps vehicles negotiate the curve at a higher speed without relying on friction.
