a lever is a ringed bar  that rotates about a point 
all levers have 3 main parts 
the place where effort is applied 
the he fixed point the lever rotates from called the pivot of fulcrum 
the place where the thing that is moved is located ]]> 2017-10-26 00:48:57 UTC https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/200651455 class levers mrolfe https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/200653269 2017-10-26 01:01:33 UTC https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/200653269 friction mrolfe https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/202749792 friction is a friction  is a force of resistance 
to the motion of an object 
-friction happens when two surfaces touch each other 

-in machines friction occur where two surfaces slide or roll on each other

-some machines use oil to lesson frictions]]> 2017-11-02 00:54:23 UTC https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/202749792 machine friction mrolfe https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/202750742 -in machines friction occur where two surfaces slide or roll on each other

absorb some of the heat produced by frictions and spreed it around]]> 2017-11-09 01:00:46 UTC https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/205104735 bike tires mrolfe https://padlet.com/mrolfe/g2o5dhv4zcc1/wish/205105600 bike tyers come in diffrent shapes and sizers
