Turning one gear causes another to turn in the opposite
direction
Used to transmit the rotational effect of a force from one
place to another
Different sized gears can be used to change the moment of
the force
Force transmitted to a larger gear will cause a bigger
moment, asthe distance to the pivot is greater
Larger gear will turn slower than a smaller gear
Gears
Smaller input gear turnign a larger one
Second gear will turn faster
But with less force low gear
Opposite direction
Larger input gear turning a smaller one
Turns slower
More force Larger gear
Opposite direction
Two objects collide and stick together
Examples - two train carriages colliding and coupling together
Collide and stick
Add together the momentum of the two seperate objects at the
beginning, and equate this to the momentum of the single object
at the end
