What is the work done by a machine called?
The work you do on a machine is called the input work, and the work the machine does in turn is called the output work. A machine’s is the ratio of its output work to the input work.
Is it true that the work done to a machine is input work?
The work you do on a machine is called the input work, and the work the machine does in turn is called the output work. A machine’s is the ratio of its output work to the input work. An ideal machine would be 100 percent efficient. All of the input work would be converted to output work.
When a machine is used to do work the force applied by the machine is called?
efficiency. ratio of resistance force to effort force. mechanical advantage. device that does work with only one movement. simple machine.
Is work always done with a machine?
Machines and Friction You can never get more work out of a machine than you put into it. In fact, a machine always does less work on an object than the user does on the machine. That’s because a machine must use some of the work put into it to overcome friction.
How does a machine do work?
A machine is any device that makes work easier by changing a force. Machines may increase the strength of the force, increase the distance over which the force is applied, or change the direction in which the force is applied. Machines that consist of two or more simple machines are called compound machines.
What is input work?
Work input is work done on a machine equal to the effort force times the distance through which the force is applied. Work output is work that is done by a machine equals resistance force times the distance through which the force applied.
When work is done work output?
In physics, work output is the work done by a simple machine, compound machine, or any type of engine model. In common terms, it is the energy output, which for simple machines is always less than the energy input, even though the forces may be drastically different.
Why the work done by a machine be greater than the work done on the machine?
Work output can never be greater than work input. Machines allow force to be applied over a greater distance, which means that less force will be needed for the same amount of work. When a machine changes the size of the force, the distance through which the force is exerted must also change.
What makes a machine a machine?
A machine is any physical system with ordered structural and functional properties. It may represent human-made or naturally occurring device molecular machine that uses power to apply forces and control movement to perform an action.
What is used when force is applied?
Answer: ENERGY. Explanation: BECAUSE IF ENERGY IS NOT USE YOU CAN NOT APPLY FORCE.
What is meant by work done?
work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.
How is work done?
Work is done when a force that is applied to an object moves that object. The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that moves an object 3 meters, does 30 n-m of work. You have to exert a force AND move something to qualify as doing work.
