Move the two on the outside of the line of 4 to the line of 2. Then move the single pin from the line of 1 in front of the new line of 2.
Line 1: Start: 1 pin End: 0 pins
Line 2: Start: 2 pins; End: 4 pins
Line 3: Start: 3 pins; End: 3 pins
Line 4: Start: 4 pins; End: 2 pins
Line 5: Start: 0 pins; End: 1 pin.
Because there's no such thing as "really" stationary or "really" moving. If the distance between a point on one train and a point on the other train is changing, then a person on either train says that the other train is moving, and both of them are correct. A "stationary" train only appears to be moving if the train you're on is moving relative to that one.
Bowling, like golf, is an OFFENSIVE sport only. There is no DEFENSE in bowling.
It is not only possible---it will stop moving at some point in the far distant future.
Deciding if an object is moving isn't as easy as it sounds. We can only discern relative motion and we have to use reference points. (A reference point is an object that is not moving that you compare to the other object.) An object is in motion when it's distance from the reference point is changing.For example, you could say that you and this computer are not moving. Other than your eyes blinking, chest pumping up and down, and you clicking on the mouse, you and this computer are not in motion. Since the distance between you and the computer is not changing, you can conclude that neither you or the computer are moving.
A swinging pendulum is moving fastest at the lowest point of its arc. That is the point where all its potential energy has been converted into kinetic energy, and it is the only point in a pendulum's arc where that happens. See related link (a simulation).
Objects are always moving. The earth is moving and so everything on it. Nothing even off the planet ever stops moving because ALL motion is relative. Something is only not moving relative to something moving the same way.
Stationary is only meaningful in regard to a defined "Reference Frame", or "Point of Reference". The object is not moving relative to that Frame or Point.

Relative means it depends on the person's reference frame/point-of-view. For example, when you're in a moving car, your point-of-view tells you that the car is not moving at all (after all you're inside the car all the time, you only know the car is moving because the objects outside the car are moving against you). But another person standing on the sidewalk will see your moving car as moving at, say, 50 mph.
No, there are other ways of reversible, such as moving
Only if it has a stream or other source of moving water running into or out of it.
The vertical velocity is zero at the highest point. It has ceased moving upward and will begin moving downward. Gravity and air resistance will have negated the original vertical velocity (y-component). So the velocity at the highest point has only a horizontal or x-component.
