no, it's moving away from the earth by 10cm each year

No it will not.
Friction by the tides is slowing the earth’s rotation, so the length of a day is increasing by 0.002 seconds per century. This means that the earth is losing angular momentum. The Law of Conservation of Angular Momentum says that the angular momentum the earth loses must be gained by the moon. Thus the moon is slowly receding from Earth at about 4 cm (1½ inches) per year, and the rate would have been greater in the past. The moon could never have been closer than 18,400 km (11,500 miles), known as the Roche Limit, because Earth’s tidal forces (i.e., the result of different gravitational forces on different parts of the moon) would have shattered it. But even if the moon had started receding from being in contact with the earth, it would have taken only 1.37 billion years to reach its present distance.
NB: this is the maximum possible age — far too young for evolution (and much younger than the radiometric ‘dates’ assigned to moon rocks) — not the actual age.

No. In fact, the moon is slowly moving away from Earth. The moon creates a tidal bulge on the Earth, and because of Earth's rotation, the bulge is always slightly ahead of the moon. This causes the moon to speed up, because it's attracted to the bulge, and that boosts it's orbit. It moves away from us (now) a little over an inch a year. The moon is about 3 1/2 feet further now than when Neil Armstrong first stepped on it in 1969.

Actually the moon is pulling away from the earth a little each year. In a few million years we may actually lose the moon entirely. Only one way the moon can ever collide with the earth and that is if an asteroid hits the moon with enough force to drive it into us, close enough the earth will actually pull it in with the force of its gravity.

No. The moon is moving away from Earth at a speed of about 1 1/2 inches (3.8 centimeters) per year.

The moon is slowly moving away. It was much closer billions of years ago. The interaction of the moon with the earth is slowing down earth's rotation and by conservation of angular momentum the moon moves farther away. Only a few inches a year but it adds up over millions of years.

i would say no, but there is possibility, that once the moon has expelled itself from earth gravitational pull.
that if it remains in the same sun orbit close to the earth there could be a possibility that the moon will have close encounters when that happens, to see what exactly will happen devise a program of the moons sun orbit in conjunction to the earths sun orbit, once the moon is released from earths gravity pull.
interesting project that would be. :)

I read that the Moon is steadily receding from the Earth so I'd have to say no it won't collide with us.

I have heard that the opposite is true. The moon is very gradually moving further away from the earth.

No. The moon is actually getting gradually further away from the earth.

No in fact the Moon is moving away from us at about one centimetre a year. This as been proven by scientists reflecting laser beams of mirrors left by the Apollo astronauts in the late seventy's.
