Machine
Practice Version
Machine:
A device that makes work easier by changing the size or direction or both of a force. Machine. A machine is something that helps us do things more easily, like lifting a heavy box.
Example:
Imagine trying to open a tightly sealed jar of pickles. Just like how you might use a rubber grip or a towel to make it easier to twist open the jar, a machine like a lever or a pulley helps make work easier by changing the size or direction of the force you apply. In both cases, the tool (rubber grip/towel or machine) reduces the effort needed to accomplish the task by either increasing your grip or changing the force direction, showing how machines simplify tasks by amplifying human effort.
