How Did the Egyptians Build the Pyramids?
The Mystery
With materials being mined 960 kilometers away, huge rocks had to be hauled to the top of this massive structure. But how would a civilization with no working engines move rock slabs that weigh 2 TONS each to the top of a pyramid 146.5 meters high? Your Challenge Using the materials available, and without lifting the text books, move them from the floor to the top of a chair using the least amount of force. Remember to measure the force with a newton meter! |

The Inclined PlaneWhat is an inclined plane?
How does it decrease the force needed? (FORCE VS DISTANCE) What would happen if you made the ramp shorter? Longer? Give some examples of inclined planes. |
