Balance of Forces
What would happen if the gravitational force were greater than it is
today? Running or walking would be impossible. Humans and animals
would spend much more energy moving about, which would diminish the
energy resources of the earth. What if gravity were less powerful? Light
objects could not maintain their state of balance. For instance, dust particles
picked up by breezes would float in the air for long periods. The speed of
raindrops would decrease, and they possibly would evaporate before
reaching the ground. Rivers would flow more slowly and hence electricity
would not be generated at the same rate.
All this is rooted in the property of the gravitational pull of masses.
