Machines
The film discusses various simple machines, including the wheel and axle, lever, pulley, inclined plane, wedge, and screw, and how they are used to make work easier. It provides examples of these machines in everyday objects and activities, such as bicycles, door knobs, pulleys, levers, and inclined planes. The film emphasizes that these simple machines are the building blocks of all machines, from lawnmowers to railroad engines, and they help us push, pull, or move things from one place to another.
