What is a Simple Machine?

The video tutorial explains the concept of simple machines, which are basic tools that help increase force. It covers six types of simple machines: inclined plane, lever, wedge, wheel and axle, pulley, and screw. Each type is described in terms of its structure, function, and how it provides a mechanical advantage. The inclined plane reduces the force needed to lift objects, while levers transfer force to lift heavy weights. Wedges direct force sideways, and the wheel and axle system facilitates movement. Pulleys make lifting easier, and screws use threads to modify force.
