The question was:
What will happen to Earth if it rotates twice as fast as it does now?
Our findings were:
1) Gravity is not effected by the Earth's rotation.
2) Centrifugal force depends on the spin rate.
3) Centrifugal force = force pushing out from something.
4) Earth would have to spin 17 times faster for objects to fly off into space.
Conclusion:
We would feel lighter if the Earth spun twice as fast as it does now because of the centrifugal force. However we would not fly off the planet and time would go slower.
After we had found out the answer Mr Lietze took us outside to play. We poured water into a container and spun around in circles to see how the centrifugal force kept the water in the container. Check out the pictures!
