In what two ways can machine change the way work is done?
machines change the way work is done, in what two ways can a machine accomplish this? By changing the size and direction of force. What is the difference between input force and output force? Input force is the force exerted on a machine, and output force is the force a machine exerts on an object.
How does a machine affect the work completed?
A machine does not decrease the amount of work that is done. Instead, a machine changes the way in which work is done. Recall that work is the use of force to move an object. If, for example, you have to lift a heavy box, you can use a ramp to make the work easier.
What are 3 ways that machines change the way we do work?
There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied.

What are the three ways in which machines help us?
(i) A machine can be used to obtain a gain in speed. (ii) A machine can be used to lift a load in one direction by applying an effort in a convenient direction. (iii) A machine can be used to lift a heavy load by applying a less effort.
How machines can help us in four ways?
Machines are useful to us in the following ways: (1) In lifting a heavy load by applying less effort. (2) In changing the point of application of effort to a convenient point. (3) In changing the direction of effort in a convenient direction. (4) For obtaining a gain in speed.
How tools and machines help us in our daily lives?
