4. A simple machine used to change the amount of force needed to move the object e.g your arm
6. The amount of work you put into the load, also called a class 3 lever it is the amount of work you use on an action e.g your hand
7. The load on a object, also called a class 2 lever it is where the object is getting work done to it e.g a crate of oranges
8. A pivoting point in the lever, also called a class 1 lever where the lever can move around on a point e.g the bolt in a pair of pliers
9. A closed system where a load is pushed by air, it starts out with a big push, then gradually pushes in it's direction e.g like the doors on a school bus
10. A contained place covered with borders to trap or put something in e.g a fence
11. Known as a ramp, it helps to decrease friction and helps to use less effort needed to lift the load
14. A closed system where a load is pushed by liquid through a tube/a pipe e.g a dentist chair

1. A pulley that is not attached to a object, it reduces the effort used to lift the weight up
2. A pulley that is attached to a object, it doesn't move and is used to lift a load
3. A circular wheel that has a space around the circumference that allows rope, belt or chains to pass around it, mainly used to pull up and object e.g a crane
5. The quotient of the force applied to the load to the force put in the system/ the effort you use
12. Pulley A mix of two different pulleys, it reduces that effort tremendously, but it takes a long distance to travel
13. This is when pressure is applied to a part of a fluid, it is transported to all the parts of the fluid, no matter the container e.g a balloon
