## When work is done by machine it is called?

4. The work done by the machine on another object is called the work output.

**What simple machine is a chair?**

screw simple machine

Screws can be used to lift things or to hold them together. Examples of the screw simple machine include swivel chairs, jar lids, and, of course, screws.

### Is the work done on the machine *?

Work is defined as the product of force and displacement… The work done on the machine at the effort end is called the work in and the work done by the machine at the load end is called the work out .

**What is the formula for simple machines?**

Calculating Mechanical Advantage and Efficiency of Simple Machines. In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr.

## Why is work done with a machine is the same as work done without a machine?

The total amount of work remains the same whether it is done with a machine or not. You can think of this in terms of the formula for calculating work—work is force times distance. Because a machine does not decrease the amount of work to be done, less force must mean greater distance.

**When does work take place in an object?**

Work is done when a force is applied to an object through a distance. This means that when a force is applied to an object through a distance, the object’s total energy will be affected.

### What is the definition of work in physics?

Work is the transfer of mechanical energy from one object to another. Since work is a change in energy, it is measured in the same units as energy: joules (J). The definition of work in a physics context is quite different from how it is used in a person’s daily life and is as follows:

**How is the kinetic energy of an object related to work?**

The change in the kinetic energy of an object is equal to the net work done on the object. This fact is referred to as the Work-Energy Principle and is often a very useful tool in mechanics problem solving. It is derivable from conservation of energy and the application of the relationships for work and energy,…

## Which is the simplest case of mechanical work?

The simplest case of mechanical work is when an object is standing still and we force it to move. The energy of a moving object is called kinetic energy. For an object of mass m, moving with velocity of magnitude v, this energy can be calculated from the formula E= 1/2 mv^2. There are two types of energy in many forms:
