As a patrolman
A book is not considered a simple machine as it does not have moving parts that work together to perform work. Instead, a book is a tool for conveying information, stories, or ideas through written text.
A MacBook is considered a laptop. If your asking if a Windows machine is better then a Mac machine then only you can answer that. Do your home work and look at both.
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
The work done on a machine is called input work or mechanical work. It refers to the energy transferred to the machine to operate it and perform tasks.
If the input work is processed by a machine and no output work is produced, the machine is considered to have zero efficiency. This means that the machine is not effectively converting input work into useful output work.
Friction :) it says so in in my science book.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
the work a machine does is the work output what it takes to do the work is the work input
It is the efficiency of the machine.
The energy that is used to make the machine work.
The work input for a machine is the amount of energy or force that is put into the machine in order to make it operate. It is the energy that is required to do work on the machine and make it perform its intended function.
