1. The effort distance, effort force and the amount of work decreases When we use the lever.The farther we were away from the fulcrum the more all three of them increase.
2. They make are life's easier by decreasing the amount of work we have to do.
3. The motor could lift more washers using the lever than when it was lifting by itself. we moved the motor so it was opposite the sled on the other side under the lever. the motor could not lift the sled and 10 washers, so we took some off. our motor lifted 5 washers and the sled. so my conclusion is the motor lifted more washers using the simple machine, (lever), than it did by itself and it took less effort and work when using the simple machine.

1. It lights up
2.i think the more washers there are the the lightbulb will be brighter.
3. # of washers. What I saw
4. The light bulb lit up, kinda dismiss.
5 The light was brighter
6. The light was bright
7. The light was really bright=http://!
4.the more weight there is on the motor the more electricity it generates.
5. The electricity is coming from the string pulling on the motor really quickly as if the motor was running. The more weight ( washers) that pulls on the string the faster it will go. The more speed the more electricity.
6. # of washers. Weight of washers Distance fell. Work
4. 1.0. 107 cm. 10.7
5. 1.5. 107 cm. 71.5
6. 1.58. 107 cm. 68
7. 2.0. 107 cm. 53.5
7. The more weight on the motor the faster it goes and the more electricity the Motor genertates
8. i think the light bulb would be waaaay brighter if the washers had a shorter distance to fall,(shorter string).More washers,stronger motor.
9. i think you should...
1) multiply the weight of the washers by the distance they fell.
this is the work.
2) now divide the number you got for work by the time it took for the washers to fall.
this is the power.
10. yes you can i think because you could connect the wires to the battery set up.the energy would flow up the wires and the washers would fall and the light bulb would light up.

i think the difference in the every day work and the deffintion of work is in every day work is also mental labour as well as physical. the defenition of work is puting in effort to move something.

I learned that controlled variables are when you just adjust one or a few things.When you do this you can see how that one thing affects your data.
i know that we were measuring friction because even though the block weighed the same thing all the time we pulling it, when we pulled the block on different surfaces the weight appeared to vary.
If you used one block and slid it on ice there wouldn't be a lot of friction because the block would have nothing to grip on. if you added more blocks i think you would be adding a little bit more, because each block added is more weight pushing down on the ice.

I believe how the English language is used in America is getting worse and worse. Slang use of words is replacing the real ones.Words like "Gonna", and " "is whats becoming normal. Schools are not doing as much as they could to make sure kids know the proper language. I think knowing and using the proper English language is important. When time comes to apply for a job they will not just be judging how well you can preform in the position, they're also listening to how you talk. if you sound like you've just come off the streets, chances are you won't get the job. This is why I believe using the proper English language is important.

so i was just having a normal day at school.60 percent working and 40 percent talking. i was in science and we were all sorta listening to the substitute when we all here a crash out side.i peer out the window and i blink a couple times. A UFO? the door flys open. in comes 9 freaky looking creatures. they all start talking at oncs but the words are all togather. they say "our names are" then they each say their names "heat" "light" "sound" electrical" "kinetic"elastic" "gravitational" "nuclear" chemical. do you know us? " i looked around the room at every one. but the were all under the tables. its not a earth quake! "take them!" electrical said. "they need to know us!" so i watched all my class mates being loaded into their space ship. so thats the reason im the only one here today! whats that you say mr g? every one else is here? never mind then......

the motor required more energy. we found this out by timing how long the light bulb stayed on and how long the motor stayed running.each table recorded this data then we found a class average for each. we compared our averages with the other classes and even though the numbers were different, the motor dropped out first on both of ours.so the motor requires more energy to run.

so we had all our supplies
:zinc strip,copper strip,blotter paper,rubber band,tape,two wires connected to a grain light bulb, and a cup of copper sulfate.
then we rubber banded the zinc strip on one side the blotter paper in the middle and the copper strip on the other side.the rubber band wrapped around one end.then we bent the other end of the copper and zinc strips out ward to it looked like a ear of corn.we taped the end of one of the wires to the zinc strip and the end of the other wire to the copper strip. after that we dipped the end of the strips and blotter paper with the rubber band on it in to the copper sulfate. and wala! the tiny weeny bulb lit up! after a little while we took the battery out of the solution and laid it on a paper towel. the light bulb stayed lit up! eventully the light flickered out.
