gravity keeps us on Earth!
The
Magnet
The effects of gravity can be explain as a gigantic magnet
in the center of the earth, always pulling and tugging on
things. If a car traveling at 50 miles an hour is experiencing
5.4 g's and a car experiencing 0.4 g's are driving down the
same road then the car experiencing 0.4 g's will be going
faster right, wrong. Think about walking on earh, now think
about walking on the moon. What will happen is, the car with
0.4 g's will start accelerating and lift off the ground, and
the car with more g's will eventually pass the second car
as its spinning its wheels in the air. The effects of gravity
hold people on the ground, cars on the ground, everything
on the ground.
Positive
G's
If you're walking on the sidewalk going to your first hour
class, Mrs.Wubbena and suddenly your spine gets smaller and
you go from 5,10 to 4,4 and then it snaps. This is a result
of positive g's. Instead of floating off the ground, you're
pulled closer to it, and kind of smashed if the g's are too
great. Engineers pay very close attenetion to make sure the
g forces aren't too great on rollercoasters.
