    Input Work
In summary, input force is the amount of force applied to an object or system. Input work is the work done on a body or system, typically measured in force times distance, and adds energy to the object. This is in contrast to output work, which is a force applied by the body or system to something else. Input work can be calculated using the formula force x distance, or by calculating the impulse, force x time, and using that to determine the work done.

okay so input force is the amount of force that is put in right?
so you can find that by using the formula force = mass x accleration...
but then what is input work?

work is the result of force... but then wouldn't that be output work? i don't understand teh concept of input work... what is it? how do you find it?

Umm, I'm unfamiliar with your terminology but I think what you're getting at is this:

Input work would be the work done on a body or system, that is, forces that are applied to the body or system. This is in contrast to output work which is a force that is applied by the body or system to something else.

There are two ways you can apply force to an object:
1) Force times time dt is called an impulse and adds to the momentum of the object.

2) Force times distance dx is called work and adds energy to the object.
 

1. What is input work?

Input work refers to the amount of energy or effort put into a system or process. It is a measure of the force applied to an object multiplied by the distance it moves in the direction of that force. In simpler terms, it is the work done by a person or machine to complete a task or operate a system.

2. How is input work calculated?

The formula for calculating input work is W = F x d, where W is the work in joules, F is the force in newtons, and d is the distance in meters. It is important to note that the force and distance must be in the same direction for the calculation to be accurate.

3. What are some examples of input work?

Examples of input work include pushing a shopping cart, lifting weights, pedaling a bicycle, and typing on a keyboard. Essentially, any activity that requires effort or energy to be put in can be considered input work.

4. How is input work different from output work?

Input work and output work are two sides of the same coin. Input work is the energy or effort put into a system, while output work is the energy or work that is produced by the system. Input work is often used to power a machine or perform a task, while output work is the result of that input.

5. Why is understanding input work important?

Understanding input work is important in many fields, including physics, engineering, and biology. It allows us to analyze and optimize systems, and helps us understand the relationship between force, distance, and work. It also plays a crucial role in understanding and improving human performance and efficiency.
