have your brakes checked
When a car squeals while moving, but the brakes still work properly, it could be a squeal from a drive belt. It could also mean that something like a tire rim is rubbing on the brake rotor. A vacuum leak in a small hose under the hood will also cause a squealing noise.
I'd have those looked at while your car still stops
It is the law of inertia bringing you forward while the car stops, the law of inertia states that an object at rest tends to stay at rest, while an object in motion tends to stay in motion.
Check that the fan belt is tight.
something is obviously touching rotor when you brake. Take wheel off and check by spinning rotor.
No, brakes and rotors are not the same component in a vehicle. Brakes refer to the system that slows down or stops the vehicle, while rotors are the discs that the brake pads press against to create friction and stop the vehicle.
There may be damage or misalignment in the front brakes if this is where the sound is coming from. If it is from more generally under the hood, this can be the power steering.
Check your brakes and CV joints
Because a body in motion tends to stay in motion. See the link, The Car and The Wall.
Cantilever brakes and V brakes are two types of bicycle brakes that differ in their design and placement on the bike. Cantilever brakes are mounted on the frame or fork of the bike, while V brakes are mounted on the seat stays or fork. V brakes typically provide more stopping power and are more effective for quick and powerful stops compared to cantilever brakes.
You should have your brakes cleaned! Or have a mechanic look to make sure nothing is wrong. My neon does this and after driving a while it stops. Sometimes rust,dust and dirt particals get on the drums !!
Check to see if engine is getting fuel and spark
