The phrase "acceleration is needed" is correct and usable in written English.
You can use it when discussing the necessity of increasing speed or progress in a particular context, such as in a project or process.
Example: "In order to meet our deadlines, acceleration is needed in the development phase."
Alternatives: "speed is required" or "increased pace is essential."
Aggressive acceleration is needed far less often in encounters in the city's stressful traffic circles.
From these results, further acceleration is needed to achieve stable and visually acceptable simulation.
For the effective removal of submicron particles, a higher level surface acceleration is needed since the adhesion forces (mainly van der Waals force for dry surfaces) are related to the particle size and increase approximately linearly as the characteristic radius of small particles that are to be removed decreases.
In this experiment, we aimed to establish whether lateral ball acceleration is needed to account for the observed movements.
Whenever more than a slight amount of acceleration is needed when in a high gear (relative to the speed), it saves fuel to downshift to a gear suited to the needed acceleration.
Because there is no air resistance on the moon, reverse acceleration was needed to stop forward progress.
In my test car, as soon as the 6-speed sensed that no additional acceleration was needed, it dropped into sixth gear to save fuel.
Furthermore, large yaw range, velocity and acceleration were needed for replicating the recorded maneuvers.
Although with noisy measurement of line of slight rate the isolation of the input is not possible, the detection filter designed for the noise-free case succeeds to provide a satisfactory estimate of target acceleration, which is needed for an improved homing performance.
During acceleration high traction power is needed while when cruising with constant speed traction power is only needed to overcome the resistance forces.
The technology involves turning off four of the engine's eight cylinders except when maximum power is needed for acceleration or towing.
