Deceleration lanes give a driver time and space to reduce their speed.
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.
The speed of the rod is proportional to the number of teeth on the cog and that which is driving the cog. If the driver remains the same then in order for the driver and the cog to mate one typically needs to reduce the number of teeth on the cog when it is made smaller. Thus the ratio of the teeth on the driver to that on the cog is increased as will its speed.
The four potential dangers drivers encounter in a work zone are reduced speed limits, lane closures, uneven road surfaces, and workers and equipment near the roadway. Drivers should stay alert, reduce speed, and follow signs and flaggers to ensure safety in work zones.
An electromagnetic wave in space does not slow down because there is no medium for it to interact with and lose energy to. In vacuum, the wave travels at the speed of light (c) as specified by Maxwell's equations.
Reduce your speed by at least half on ice to maintain control of your vehicle and prevent skidding. Drive at a cautious speed and leave extra distance between your car and other vehicles to allow for longer braking distances.

There are: 1. stop 2. speed 3. turn lanes 4. reduce speed 5. rest area ahead 6. speed bumps 7. rumble strips ahead (or in the middle)
Not usually. You could have simply changed lanes. the question said "so you speed up to change lanes"

It's used to detect if your speed is being monitored by a radar gun by the police. They are used so the driver can reduce his speed before receiving a ticket.

How it works is not nearly as important as what it does. The "how" involves distance sensors similar to radar guns, computers, and algorithms. The "what" that the driver needs to know is that it will slow the car down automatically if the car see's a vehicle in front of it getting too close, and match that cars speed. Typically the car will then speed back up to the speed set by the driver when it no longer sees that obstacle a.k.a. that car exited, sped up, or you changed lanes.

Another driver cannot "force" you to speed up or change lanes without driving very dangerously indeed, in which case note his registration and try to stay safe yourself. Just because someone behind you obviously wants to go faster, you don't have to, especially if you're already near the speed limit. Drive safely and for yourself. If the driver in front slows down and it's not safe to pass, you just have to slow down too. Don't use your horn to start an argument, only to let him know you're there (if you think he may not have seen you).
