What is coasting in a car?

Letting gravity roll the car along... as on a hill or gradient.... and with the engine off or the gears in neutral.


How does a height of an inclined plane affect the speed of a car?

A high hill will usually slow a car more than a low hill will, if the angle of the incline is the same, and if you don't mess around with the accelerator pedal.


How does changing the incline of a hill affect the speed of a car?

Increasing the incline of a hill will typically slow down a car due to the increased gravitational force that the car must overcome. The steeper the incline, the more energy the car must expend to climb, resulting in a decrease in speed. Conversely, a downhill slope will generally increase the speed of a car as gravity assists in pulling the car downward.


Does the height of the ramp affect the speed of the car?

Yes,if you are going at 100 mph and you go down a steep hill your speed on speedometer does not go higher but your car actually gains speed no it does not, the height of the ramp affects the distance ,not the speed.Laws of physics apply here.


Does the placement of the wheels on a car change the speed of the car?

The placement wouldn't affect the speed, but would affect the handling.


How does the size of a toy car affect its speed?

It would affect its speed because the weight of the car is gonna slow it down


When does gravity affect your car speed?

Gravity affects your car speed when you are driving on a hill. When going uphill, gravity acts against the car's momentum, causing it to slow down unless the engine compensates with more power. When going downhill, gravity assists the car's momentum, causing it to speed up unless the brakes are used to control the speed.


Does the height of a car affect a car's speed?

The height of a car itself does not directly affect its speed. However, factors such as weight, aerodynamics, engine power, and tire size can impact a car's speed. A higher car may experience more air resistance, which can affect its top speed and acceleration.
