ACCELERATING : increasing in speed or velocity, or (analogous use) a trend that increases more rapidly e.g. "The deforestation of Brazil may be accelerating." (applies to the rate of deforestation)
Roger the rabbit ran rapidly. Rattling rain, rattling the window panes. And of course: Round the rugged rocks the ragged rascal ran.
Bad ground somewhere
Gee, she's a real chatter box. When the squirrel saw a nut he began to chatter. They went on and on chattering about their dead plants. Chatter= to talk rapidly or incessantly on trivial matters
The rattle consists of loosely connected scales - when the snake moves it's tail rapidly, they scales rub together producing the classic rattling sound.
Automatic-rifle bullet are usually gas powered and the achieve great speeds by rapidly accelerating out of the rifle, usually in response to a trigger.
Input energy: The jet plane usually uses the chemical energy in some fossil fuel.Output energy: "Accelerating" means that its speed increases; that means that its kinetic energy increases. Energy is also wasted when burning the fuel, as heat; and the plane wastes energy through friction.
einsteen's theory of relativity  extended maths to cover objects moving at a constant high speed.His general theory of relativity further extended the maths to cover rapidly accelerating objects.
The over excited metal-molecules are rapidly accelerating when the metal is heated, and this excitement caused them to collide more frequently than usual and in more drastic and random motions. The increase in kinetic energy promotes expansion.
more rapidly and most rapidly
