- You don't notice MOND near massive bodies because the acceleration is too high.
- Yeah, the centrifugal acceleration is dependent on the radius.
- And by definition when your speed changes, it's an acceleration.
- But strictly speaking it's wrong because you can't just redefine what you mean by zero acceleration.
- And so most of the paper is devoted to working out whether solar radiation pressure could explain this acceleration in a moment.
- You're propelled through the world with fixed acceleration.
Examples
-

acceleration = accelerate (transparent) = accelerate + ion
The physics sense is a direct nominalization of 'accelerate' describing the process/rate; although technical, it follows the normal verb → noun derivation.
Etymology
Acceleration comes from the parts ad- 'to' and celer 'quick', so it carries the idea of 'making quick'. That's why, in physics, acceleration describes how fast an object's speed or direction changes.
