When you push or pull with a simple machine, you are applying a force and doing work. And, if you get more force out of a machine than you put into it, then that machine has a mechanical advantage.

A simple machine is a mechanical device that changes the direction or magnitude of a force. In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called ...

A simple machine is a tool that helps us do work. They use clever shapes to help us move, lift, cut and other types of work. Learn more about the inclined plane, the pulley, the lever, the wheel and ...

Introduction: This lesson provides students with a review of simple machines and their tasks. It works best in combination with your lesson on simple machines, or as a review/additional activity.

Introduction Before the industrial age people largely had to rely on muscle power to move and lift heavy objects. Simple machines such as pulleys, levers and ramps made it easier for humans to lift ...

WAAAAAYYY back when I was in middle school physics they had some programs on our school computer that let you build simple machines. We basically built Rube Goldberg machines in the simulator to test ...

Machines are all around us, helping us do tasks and work all day, every day. The most basic ones are deemed “simple machines,” but these were, and still are, some of the most essential technological ...

A new children’s book, titled Simple Machines Made Simple, wants to demystify mechanical engineering for kids as young as a year old. It recently beat its Kickstarter goal by 700%—raising more than ...
