A description of how to write up a science report for the simple machines unit

Measuring the force required to pull a weight up an inclined plane, controling for variables and repeating 12x.

Balanced forces=no change in speed or direction; L x Force=L x Force

3 Classes of Levers

Effort Force, Output Force, Fulcrum

The Pulley changes the direction of the force, and the input force depending upon the number of ropes pulling the weight or output force.

def of lever, pulley & combined and examples of combined simple machines

Archimedes screw & Wood screw

Explaination of experiment & ideas about what to control.

Create two groups by controlling everything and change only one thing to make a fair test

Axle, input force, output force

The difference between a wheel or roller compared to a wheel & Axle, and the mechanical advantage of a wheel and axle comes from the ratio of the ...
