where from?
You can accelerate by increasing your speed, boosting your acceleration, or reducing air resistance to minimize drag.
air
Not all moving objects accelerate. In general, an object will accelerate if there is a net force acting on it. For a ball in the air, this might be gravitation + air resistance; for a moving car (once you turn the engine off) it might be the force of friction; etc.
A dirty air filter will cause your automobile to not properly accelerate. A dirty fuel filter will also cause your automobile to not properly accelerate.
By increasing the firing in the Turbine.
Heavier than air objects accelerate downwards. Lighter than air objects accelerate upwards until they are no lighter than the air around them.
Terminal velocity describes the point at which an object in free fall will no longer accelerate due to air resistance.
much less air resistance.
Gasoline pedal/air intake pedal
Yes. Air is matter. It takes force to get air to accelerate indicating that it has mass, and trying to compress it in a container shows that it takes up space.
maybe clogged air filter or carburettar is sucking air and needs repairing
Objects in free fall in a vacuum accelerate due to the force of gravity acting on them. In the absence of air resistance or other external forces, the only force acting on the object is gravity, causing it to accelerate at a constant rate of 9.8 m/s^2 towards the Earth's center.
