Question

banked roadways help overcome this force.

choose the category below that the above fact relates to.

inertia
potential energy
gravity
cen

Explanation:

Analyze the physical scenario

The question states: "Banked roadways help overcome this force." We need to identify which physical concept or force this statement relates to from the given options.

Understand banked roadways

When a vehicle travels around a curve, its Inertia in Crashes (or general inertia) wants to keep it moving in a straight line. From the perspective of the rotating frame of reference of the vehicle, this manifests as an outward centrifugal force pushing the vehicle toward the outside of the curve.

Evaluate the options

• Inertia: Inertia is the tendency of an object to resist changes in its state of motion. While inertia is the underlying reason a car wants to go straight, the specific outward "force" felt during turning is centrifugal force.
• Potential Energy: This relates to stored energy due to position, which is not the primary force overcome by banking.
• Gravity: Gravity pulls the vehicle downward. On a banked curve, a component of gravity acts inward, helping to provide the necessary centripetal force. Thus, gravity helps overcome the outward force, rather than being the force overcome.
• Centrifugal Force (partially cut off as "Cen..."): This is the apparent outward force acting on a vehicle moving along a curved path. Banked roadways are tilted inward so that gravity can help counteract this outward centrifugal tendency, reducing the reliance on tire friction alone to keep the car on the road.

Select the correct category

The partially visible option "Cen..." represents "Centrifugal Force", which is the force that banked roadways help overcome.

Answer:

• Inertia
• Potential Energy
• Gravity
• Centrifugal Force (Correct answer)
