Once upon a time a person needed to move something heavy. He or she picked up a long stick and stuck it under the edge of the heavy object and then pushed down on the other end of the stick. And the first simple machine was invented. Simple machines are just that. The simplest form of using one thing to accomplish something faster or better. A tool. They were the first ones created and we still use them today.

Jared continues our series about simple machines by exploring what the wedge allows us to do.Are you a teacher? Click here to explore our teaching resources!. Dump truck ladder roller coaster A wedge is a type of simple machine.A wedge is two inclined planes that are back to back.The difference between an inclined plane is that it does its work by staying still, while a wedge moves. Simple machines magnify, spread out, or change the direction of force, making it easier to move, cut and bind objects. Other common examples of wedges include shovels, teeth, some screwdrivers, a saw, a needle, scissors, and ice picks; or wedges that hold things together like staples, push pins, and tacks. (6) WEDGE A wedge is wide at one end and pointed at the other to help cut or split other objects. Examples of wedges: a knife or an ax Now you know about the 6 types of simple machines: (1) LEVER (2) SCREW (6) WEDGE (3) PULLEY (4) WHEEL & AXLE (5) INCLINED PLANE These simple machines make work easier! Can you Name them? The wedge is the active twin of the inclined plane and one of the six classical simple machines. Unlike an inclined plane, which is stationary, a wedge does useful work by moving. A wedge is made up of two inclined planes. These planes meet and form a sharp edge. For a wedge, the effort (force) is applied to the vertical (height) of the wedge.

There are 6 basic simple machines; the lever, the wheel and axle, the inclined plane, the wedge, the pulley, and the screw. Several of these simple machines are related to each other. But, each has a specific purpose in the world of doing work.

But what is work? Work is the amount of energy necessary to move an object. The further you move it, the more work is required. Work is measured in Newtons. More about that later. First let's look at each of the 6 simple machines in detail.
