No, due to factors such as friction, inefficiencies, and energy losses, the work you put into a machine is typically more than the work you get out. This difference is known as mechanical efficiency.
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.
Work done with a machine can make the task easier by reducing the amount of force or energy required. This means that the same amount of work can be achieved with less effort when using a machine compared to doing the work without one.
In an ideal scenario, the work done with a machine is the same as work done without a machine because the total work output must be equal to the total work input. While machines can make work easier by multiplying force or changing the direction of force, they cannot create energy. Therefore, the work done by the machine should ideally be equal to the work done without a machine.
The measure of how much useful work a machine puts out compared to the work put into it is called its efficiency. It is expressed as a ratio of output work to input work, typically represented as a percentage. Higher efficiency signifies that the machine is making better use of the energy it receives.
This is known as the principle of conservation of energy, where the total amount of energy put into a machine is equal to the total amount of work the machine can output. Due to factors like friction and heat, some input energy is always lost, making it impossible to get more work out of the machine than what was initially put in.
It is the efficiency of the machine.

Work input is how much work you put into a machine and work output is the work done by the machine according to how much work you put into it. You will never get more work out of a machine than you put into it. The efficiency of a machine is how much useful work you got out of the machine compared to how much you put in (expressed in a percent). Efficiency = Useful Work Output ÷ Work Input
This is known as the principle of conservation of energy, where the total amount of energy put into a machine is equal to the total amount of work the machine can output. Due to factors like friction and heat, some input energy is always lost, making it impossible to get more work out of the machine than what was initially put in.
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 vocabulary word for force put into a machine is "input." This refers to the energy or effort that is supplied to the machine to make it work or perform a task.
If a simple machine is 100% efficient, it means that the input work done on the machine is equal to the output work produced by the machine. In other words, all the energy put into the machine is completely converted into useful work without any energy being wasted.
