Coasting requires you to put the gear into neutral and let the car freewheel down the hill. If you came to a bend on the hill and someone was speeding up the hill, you may not have enough time to react and slam on the brakes, or slow down. When you aren't in gear, you have less control of your car, as opposed to if you was in gear. E.g. If you were in gear and slammed on the brakes, your car would stall, jerk you forward and stop, however because you aren't in gear, your car won't stop rolling.
(It's why you can push your car when it's out of gear, but you can't push it when it's in gear).
Coasting.
Gravity if you are coasting.
when you roll down a hill in neutral, like your rolling down I-80 from Tahoe to Sacramento. its safer to go down the hill in gear, since it also saves your brakes from overheating, and uses less gas.
to roll down the hill on a bike without pedaling is called coast or coasting
I was caught coasting down the sidewalk on my bicycle.
You would have to try it yourself and see. Please report back your results here.
The force of air resistance and friction from the ground act against the motion of the bicycle, eventually bringing it to a stop on a level surface. The energy that was gained while coasting down the hill is gradually lost in the form of heat due to these opposing forces.
coasting=dvizha se po inertsia /движа (спущам) се по инерция/
Go down the hill in second gear and try not to exceed 25MPH, also use the brake if the car begins to speed up past 25MPH, but do not apply/depress the clutch as this is classed as coasting and bad for the engine.
Because you roll them down a hill
Letting gravity roll the car along... as on a hill or gradient.... and with the engine off or the gears in neutral.
It saves gas. However, if you disengage the clutch on a stick shift, then you no longer have the engine controlling the wheels, and braking will be more difficult. If you turn off the engine while coasting down a hill you also remove power to the brakes and steering, and you may well lock the steering wheel accidentally. A very dangerous move!
