1.The effort increased when it got closer to the fulcrum. Was Exeter to lift.

                                                2.so you don't have to work hard to get thing were they should be when there is nothing to lift the liver

                    .  3.The moter could lift more washers useing the liver then when it lifting by itself

The best thing I did over winter brack was getting to see my cosons. My favorite gift I got was Tablet

1. It means that it's a force of energy.divide work by seconds=power.

2. Because if you have {N_M} of energy per seconds.A 100 watt meter can do 100 {N_M} Of work each seconds.

3. 1 horse power = 750w. 

4.yes because the more batteries you put on the more faster The washer it caid lift.

5. The more baterys u hade the more energy it hade.

6.they were different becouse you have to add one on as you go.

7.add more too make the moter too generate more power to the moter.

8. you hook the battiers  to the wire wich turns the energy  into electric energy.

It's newton meters The definition is work.

newton meters is N-M  in science.
