How would life be on earth if the gravitational pull was far less than it is today?
Hard to say because it affects many things. Living organisms would be built differently as they need more or less muscles to move around in such environment. Many animals would also have different survival strategies: they could simply jump really high to get away from enemies. I don't know about plant life though: would it grow much higher?
Life on earth may be completely impossible because gravity is also responsible for holding the earth's atmosphere. The moon for example, has only one-sixth the gravity of the earth which is too weak to hold onto any atmosphere it might have had in the past and so the moon is not habitable.
Just a little extra information: the moon was once part of the earth. Scientists believed that before the earth was completely formed, it was hit by a large object which blew off chunks of the earth into space which later forms the moon that we see now.

How will the human body adapt to life on Mars?The muscles in the human body have adapted to suit the gravitational force of Earth. With the gravity on Mars being 1/3rd that of Earth, how do you think the body will evolve?

What is the “speed” of gravity?Hypothetically, if one remove the Sun from its place, when the Earth would be affected? Momentary, by the speed of light or by some speed specific to the gravity...?
