The surface gravity of the moon is 1/6 that of earth's. Earth and the moon would coorbit the same point in space, if they were of equal mass (much like Pluto/Charon). I'm not sure how that would affect the tides--it would not necessarily make them higher. Both planets might be tidally locked, reducing the tides and increasing the length of earth's day.
Titan is smaller than earth, but has an atmosphere ten times as dense at its surface. But then, it is also twice as massive as our moon. This is a good question.

If the gravitational field strength at the earth's surface was the same as it is on the moon's surface, everything would be six times lighter. Unfortunately, such a weak gravity field would be unable to retain the earth's atmosphere, which would simply float off into space after a while. The seas would then follow, as the pressure dropped to the point where they boiled at room temperature. ultimately, you would end up with a life-less ball of rock, devoid of any volatile material, except at the poles where some water ice may be retained. In the absence of an atmosphere, day-time temperatures would be too hot for human life, and night-time temperatures too cold. Basically, if the earth had the moon's gravity, it would be like the moon: Dusty, dry, airless and dead. (There would be no noticeable tidal forces though- that only occurs for denser objects with MORE intense gravity fields for a given radius).

it ought to fly off in a today line in in spite of course it grew to alter into into headed on the time. Assuming gravity although labored between the Moon and distinctive bodies, despite the fact that, it may stabilize in orbit around the photograph voltaic, at extra suitable or much less a matching distance consequently of actuality the Earth. With that adjustment going on, there'd probable be a sturdy danger of it hitting the Earth someplace alongside the way - particularly consequently of actuality the Earth's orbit ought to shift some, too.

Well, first off, our bodies would be much different. We wouldn't require the thick bones or muscles for movement. We'd likely be taller, too. Things would happen much slower - things you've knocked off the table would fall 6 times *slower* than they do now. You could catch that glass before it hit the floor. Structures wouldn't need to be so strong. You could build much taller buildings with less material. Planes could use much less fuel, cars wouldn't need such big engines, and baseball fields would need to be about a mile from home plate to the edge of the outfield. You'd need gps-equipped golf balls, because you could probably knock one not 500 yards, but 3000 yards in lunar gravity. Any domed football structure would need to be about 6 times taller to avoid punts hitting the ceiling. And basketball players would need a larger court, and baskets 40 feet high to make the game a challenge.

I don't like to deal with what if questions . But for u that would probably mean that the earth and Moon ware the same mass and we would collide very shortly.

The tidal forces on earth would be unbearable. We would have tsunami like waves every time the tide would come in. I also believe it would cause massive earth quakes and massive volcanic activity.

There would be some severe tidal and weather changes but neither should be fatal.
One thing is certain we would never have landed on the moon.

We would not have a life: the earth would not be able to retain an atmosphere or an ocean. Absent these, no life is possible.
