This is what I was questioning. I would say that, say in a zero-g, vacuum environment, a moving mass would require a counter-force--acceleration in the opposite direction to its current direction of travel--but, considering something like a rolling cue ball, I don't see how the *removal* of the original accelerating force constitutes acceleration in any way. I mentioned gravity earlier, so would that be considered the accelerating force, although in a different direction?

Even if one considers a car, acceleration is achieved by using one pedal, and one can either stop using that pedal, and/or use the brake pedal--and even though that causes the use of force on the brake components at the wheels, I don't see where that equals an 'opposite' type of force/acceleration.

I'm not trying to argue that I'm right and Physics is wrong, but trying to understand WHY a mass with dwindling inertia is still considered "accelerating". Is this sort of like the equal-opposing force that is generated (if you can use that verb) by the resisting inertia of a mass--that is, when pushing on something, it 'pushes' back?

Note: I never made it to a college-level physics class, and only have passing understanding of some capital-P, Physics terms/explanations, gleaned from minor exposure, over time.

Newton's Laws of Motion:
  1. There exists a frame of reference from which, absent any unbalanced external forces, an object observed in motion tends to remain in motion at a constant velocity, and an object observed at rest tends to remain at rest.
  2. From such a frame of reference, F = m·a, force equals mass multiplied by acceleration.
  3. When one object exerts a force on another object, the second object exerts an equal and opposite force on the first object.
Velocity is a vector quantity of speed and direction. Acceleration is any change in velocity, whether that's a change in speed, a change in direction, or both. For a car (with an automatic transmission traveling on level roads, for simplicity), that means we can accelerate a car with the gas pedal, the brake pedal, or the steering wheel. Each of those controls can change either the speed or direction of the car, which is the definition of acceleration. Engaging the clutch on a car with a manual transmission allows air resistance and rolling resistance to accelerate the car. Hills allow gravity to accelerate the car.

A car traveling with a velocity of 100km/h due north also has a velocity of -100km/h due south. Both velocities describe the same motion. Consider the intersection of two straight, level roads. If a car experiences positive acceleration away from the intersection. It can be alternately and accurately described as experiencing negative acceleration towards the intersection. If we define deceleration as "negative acceleration", then the car is simultaneously accelerating in one direction and decelerating in the opposite direction.

From Newton's second law, we see that any non-zero net force* on a mass results in acceleration. The cue is not the only thing that exerts a force on the cueball. The friction from the table's cloth and, to a much lesser extent, air resistance (drag) are also forces exerted on the cue ball, and those forces also accelerate the cue ball. From the time the cue tip makes initial contact with the ball until the cue ball comes to rest, it is constantly changing speed and/or direction. In other words, it is constantly accelerating.

English notwithstanding, acceleration caused by the cue acts in exactly the opposite direction as acceleration caused by the cloth and air resistance. The cue exerts a force on the cueball in one direction. Friction and drag exert force on the cueball in the opposite direction. Which direction is considered positive is arbitrary, just a matter of perspective. We need only to be consistent throughout our calculations.

*non-zero net force: Consider a skydiver jumping from a hot air balloon. As soon as the jumper exits the gondola, he experiences positive acceleration in the downward direction, due to gravity. He also experiences air resistance (drag), a positive force exerted in the upward direction that we can describe as a negative force in the downward direction. As the skydiver's speed falling through the air increases, so does the magnitude of the force of drag. After about ten seconds, the gravitational force and the drag force will be equal in magnitude, but acting in opposite directions. At this point, the skydiver has reached terminal velocity. The gravitational force and the drag force are balanced, so there is no longer a net force acting on him; he stops accelerating and falls at a constant speed until he changes body position or deploys his parachute.
 
Holy crap. How in the heck did we collectively get so far in the semantic weeds on acceleration from an initial question about follow through?

Rhetorical question. I know how we got here and I am sorry to say I contributed. It’s AZB, that’s how. 😆

Whew wadded quickly through the 3 pages to see if I am the furst

. As this is a tip I got second hand from a coach er or instructor.
Place an empty beer bottle (a tall clear Miller bottle) on the table where the cueball would sit would be the location for the opening. Stroke through the hole and touch the bottom of the bottle without touching anything else.
Practice prac.....etc.

Greg, We disagree so seldom it seems strange! Going through a deep hole forces you to move the stick straight in all directions. Very hard to do with any stroke, particularly the pendulum. I tried a level hole, I tried tilting the hole slightly. Neither one worked real well. I had to do some very contrived manipulations of my stroke to go through a deep bottle.

After a little thought I realized I was trying to fix something that wasn't broken! While the tip needs to be straight side to side for aiming consistency, there is no reason for it to move straight on the vertical for more than a couple inches. The solution is simple. Forget a deep round hole, stroke into a channel. You can tell instantly if you have any side to side issue and you are no longer making any contact with the top and bottom of your guide. The slight vertical travel is unnoticeable when it isn't banging into glass.

Nothing is so confusing that we can't make things worse discussing it on AZB!

Some, including many pendulum stroke advocates, try to maintain that there has to be a pause when going from the back stroke to the forward stroke. True enough if something is restrained from moving up, down, or sideways. In truth, with all of the joints involved in a stroke no pause is necessary. I don't consider a pause to be a good thing, particularly a long pause. We have built a motion with our practice strokes which don't usually involve a pause, now we put a gap between the practice strokes and the final stroke. Why? (rhetorical question)

Never could get that to work for m'wah. I'm fluid. Always have been. I found it harder to control speed with a pause. It felt like starting from scratch every shot. That's just me. Perhaps I didn't give I enuf time, but I was happy with my game then so.... Today it resembles the back lot of a salvage yard, but who's saying....😉

Retard!!!!! You could use retard in place of decel. How about "downforce"? Bet you don't see that on scientific papers either. They use negative lift, it means that the air is pushing down on a car. like downforce. 😁😁

That explains what's been wrong all these years!! I'm tall so there's extra down force pressing on me.

The duration of the contact between tip and ball is very short. That's the critical part . What the tip does before and after doesn't matter as long as the strike is accurate and on the right vector.
Developing a repeatable and consistent stroke was the reason for the bottle drill.
I use rail first practice shots to tell if I have struck whitey as I intended. A slight variation in the rotation of the cueball at contact with the rail will change the path whitey takes back to me. My first rail first practice shot has me shooting from the headspot and over the foot spot with intention of the cueball returning to strike my cue tip, which awaits 6 to 8 inches past where the cueball rested at strike.
A straight rebound isn't effected by the top or bottom on whitey. Rebounding at an angle will be effected by the speed and top or back spin. An important part of warm up on a new to me table is checking the rails. Well along with the level of the bed. Shrug 🤷‍♂️.
 
Grady Mathews showed a practice drill with rail first. He might have called it the limbo. Starting with the cueball in the Jaws of the corner attempt to bank it cross side from various points on the opposite rail. How far I can open up or back up the rebound angle is good to know and development of feeling for the speed and spin required at different positions. Quit often in competition only a small portion of the rail is available when an opponent has played a safety..
Escape enough lock up safeties and Houdini could be your pool nick name.
