Neither, it depends on what you are trying to accomplish.
Well, if you had a shadow cast on earth, it would appear curved because the of the Earth's surface is curved
By, instead of a straight current, makes the current curved due to the Coriolis Effect.

As particles photons travel in a straight line unless they are diverted by reflection, refraction, or a magnetic or gravitational field. Note that when it comes to gravity it can also be represented that the light continues in a straight line - but the space it travels through is curved so its path appears curved to the outside observer.
A meniscus.
Yes, curved mirrors follow the law of reflection. The angle of incidence is equal to the angle of reflection at any point on the mirror's surface.
No. It's straight through the center of the sphere that the curved surface is part of.

Yes, the laws of reflection are applicable to curved surfaces as well. The angle of incidence is still equal to the angle of reflection, but both angles are measured with respect to the normal at the point of incidence on the curved surface.
The law of reflection is valid for any ray of light. So it is also valid for curved and flat surfaces. For curved surfaces, the normal is taken as the normal to the tangent of the point where the light ray hits the surface.
The surface should be smooth and flat to give an accurate reflection in the laws of reflection experiment. A rough or curved surface may distort the reflection, making it difficult to observe and verify the angle of incidence equals the angle of reflection. Additionally, the surface should be clean and free from any dirt or smudges that could interfere with the reflection.

Straight trimmers give you more reach and have more power for cutting tall weeds. Curved trimmers are better for tight spaces.
A tangent
A synonym for straight is unbent.
Well no it can be a straight barbell however the curved barbell contours the eyebrow better and is some what more comfortable
Yes, a cone has a curved surface, as it tapers smoothly from its circular base to a point at the top. In contrast, a pyramid has flat, polygonal faces and does not have a curved surface; its sides are made up of straight edges that meet at a vertex. Thus, only the cone exhibits a curved surface between its base and apex.
