if road conditions are bad and/or you are entering a blind curve
Road conditions are slippery
The majority of curves will begin with a warning sign and speed limit. Most importantly, slow your vehicle to the posted speed by braking before the curve. As you enter the curve, steer in the middle of your lane. Avoid hugging either sides. Half way into the curve, slowly begin to accelerate to move vehicle weight from the front to the rear which provides excellent handling and less front tire wear. Remember, prepare to control your speed before the curve, start to resume your speed half way into the curve.
Usually it is posted on a yellow diamond shaped warning sign.
Yes, you can get a SPEEDING ticket for driving too slow !

On many highways it is unsafe to continue at the normal speed limit as you go around a curve (especially for large trucks with a high center of gravity that might tip over), therefor reduced speed signs (often yellow advisory signs not the usual white legal signs) are posted indicating reasonable and safe speeds to use through the curve.
It means that you are about to enter an area where the posted speed limit is lower than the one you are in now.
The slower traffic keep right sign means that drivers who choose to drive less than the speed limit should stay in the right-hand lane. For example, 18-wheelers going up a hill often experience decreased speed because of the weight they haul. Unless passing an even slower vehicle, the slower truckers need to stay in the right-hand lane. Vehicles driving significantly below posted speed limits should also use their flashers until they are able to match the posted speed limit.

Not necessarily. It depends on the posted speed and road conditions. It would be dangerous to whip around a sharp curve in bad weather, so you are actually required to slow down and drive at a safer speed. Some curves are posted much lower than 45 if they are dangerous curves.
This is not related to physics but to the driver's attention when approaching a curve. If the speed is kept the same, it's more difficult to control the vehicle specially if the driver is stressed, drunk, tired or sleepy. The probability of an accident would increase on this situation.
