MACHINES THAT CHANGE FORCE
A simple machine is a basic tool that changes how a force works. It can make a push feel smaller, change the direction of a pull, or spread work over a longer path. You still put energy in. The machine helps you trade a big hard shove for a longer, easier push. Builders, sailors, and inventors have used these ideas for thousands of years.
