A force is a push or a pull. Forces differ in their strength. All motion (change in position or direction) is caused by force. Forces may have different names, for example, friction, gravity, electromagnetic, and centrifugal force.
Simple, compound, or complex machines are devices that help make the work easier by changing the size and/or direction of the force that is applied. There are six simple machines – inclined plane, wedge, screw, lever, pulley, and wheel-and-axle. Simple machines can be combined in all kinds of ways to create the machines we use everyday.
The science skills emphasized in Nature’s Forces Simple Machines are collecting data, manipulating, constructing models, observing, and predicting.
