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.
Simple machines allow people to make tradeoffs that reduce the amount of work necessary to perform a task. Simple machines may convert one type of force to another, change the direction of an applied force or trade distance travelled for force applied.
Machines make work easier by multiplying the force a human can exert and allowing automation of production. Simple machines, such as the lever and pulley, grant humans the ability to move objects too heavy for manual manipulation. Automation means that a single person c...
Modern automation speeds up manufacturing and makes it possible to get more work done in less time with fewer personnel. Computers and information technology have enabled an unprecedented level of access to knowledge. Transportation technology has reduced the time it ta...
Technology makes life easier through a number of developments, including telemedicine, augmented reality, product service systems and the creation of more efficient city designs. Developments in technology allow humans a range of opportunities to make life easier, more ...
A lever makes work easier because it allows a person to move an object using less force. To reduce the force that is necessary to move the object, the person using the lever has to increase the distance for the area they are applying the force.
A pulley makes work easier by redirecting and amplifying force. It helps reverse the direction of an individual’s lifting force. As a user pulls a rope down, the pulley lifts the weight up. When two ropes and wheels are used, a pulley reduces the effort needed to lift a...
