Q:

How do machines make work easier?

A:

Quick Answer

Machines make work easier by changing the force on an object. Work occurs when an individual applies force to an object, and when a machine is used, the machine applies the force to the object instead of the individual.

Machines can also reduce the amount of time it takes to perform an action by increasing the amount of force to an object. One example of a simple machine is a pair of pliers. When the two large ends of the pliers are squeezed together, the smaller ends come together to apply a greater force to cut through an object. This force is greater than an individual could pinch.

    Who first used a graph to convey information?

    A:

    Although William Playfair is often credited with having created the first bar graph around 1780, Nicole Oresme used a graph-like planar illustration in a 14th-century work to demonstrate the acceleration of an object over time. Because of similarities in Oresme's illustration to modern bar charts, his usage can be considered a forerunner of the current method of using visual elements to display numerical information. Joseph Priestly, another early proponent of using visual images to convey numerical concepts, published a timeline type of graph in 1765 that incorporated bars of varying lengths.
