If it overheats at speed, but cools down when you slow down, the problem is likely a head gasket. Combustion gasses are leaking into the cooling system, adding bubbles (which take the place of coolant) and extra heat. Slowing down means the engine is spinning slower, and less combustion gas gets into the cooling system.
check your fluids it is probably low on antifreeze and if it still does it change your thermostat that should fix the problem
Possibly thermostat is slow in opening.
No.
Check/replace the thermostat.
Because the engine is too hot to continue cycling correctly without the pistons "sticking" against the side of the cylinders, causing them to slow down or even stop moving in extreme cases. buy some antifreeze
takes the heat away from engine low coolant??
Each car overheats at a different temperature you need to look up and find out on the internet
"Brakes" make the whole car slow down.
Gravity
A parachute.
The forces that slow down a racing car are:GravityAir ResistanceFrictionAerodynamic Downforcethat's the 4 forces
A car goes faster when you accelerate. It slows down when you brake.
