Simple Machines

1. Work

1.1. The product of force and distance

1.2. Work is how far an object moves

1.3. If i push a box accross the room, the distance the box goes is its work.

1.4. If i drive a car from point a to point b the distance between is the work done.

1.5. Work=force*distance

1.6. Joules

2. 1st Class Levers

2.1. A lever being used to open something

2.2. using something to pry open something

2.3. screwdriver

2.4. seasaw

3. 2nd Class Levers

3.1. The output force is located between the input force and the falcum

3.2. when lifting up one side of something so the other side can move

3.3. wheelbarrow

3.4. moving dolly

4. Incline Planes

4.1. A slanted surface along which a force moves an object to a different eevelation

4.2. going up or down in distance but walking on a flat surface

4.3. wheelchair ramp

4.4. the ramp on a moving truck

5. Wheel and Axel

5.1. A simple machine that consists of two disks or cylinders. Each one with a different radius.

5.2. A machine with a turning end and a end that stays connected to an object moving it.

5.3. A sreering wheel in a car

5.4. a screw driver

6. Power

6.1. The rate of doing work

6.2. How long it takes to do work

6.3. If it takes me 20 minutes to mow the lawn, 20 minutes would be my power

6.4. if it takes me 10 seconds to drink a glass of water, 10 seconds is my power

6.5. Power=work/time

6.6. watts

7. Mechanical Advantage

7.1. The number of times that a machine increases an input force.

7.2. How big the input force is

7.3. A nut going into a nut cracker

7.4. A basketball going into a hoop

7.5. input/output

7.6. none

8. 3rd Class Levers

8.1. the input force is located between the input force and the falcrum

8.2. pushing or pulling something to move the opposite way

8.3. broom

8.4. hockey stick

9. Wedge

9.1. A v-neck shaped object whose sides are two inclined plain slopes.

9.2. an object that slowly closes in on its self until sharp

9.3. knife blade

9.4. zipper

10. Screw

10.1. An inclined plane wrapped around a cylinder

10.2. something that goes into to objects to keep it stable

10.3. nuts

10.4. bolts

11. Pulley

11.1. Consists of a rope that fits into a groove of a wheel
