How do simple machines make work easier?(1 point)
Responses
They magnify the force being applied, thereby decreasing the work they can do with no extra energy exerted by the person using the machine.

They increase the distance over which a force is needed, doing more work with less force.

They reduce the amount of force needed to move an object to do the same amount of work.
They reduce the amount of force needed to move an object to do the same amount of work.
They decrease the distance needed between a person and an object, allowing the person to apply more force and do more work.
None of the responses are correct. Simple machines make work easier by either magnifying the force being applied or increasing the distance over which a force is needed.
They reduce the amount of force needed to move an object to do the same amount of work.
To answer this question, simply machines make work easier by reducing the amount of force needed to move an object to do the same amount of work. This can be achieved in several ways.
Firstly, simple machines can magnify the force being applied, thereby decreasing the work needed. For example, a lever can increase the force applied to one end, making it easier to lift a heavy load.
Secondly, simple machines can increase the distance over which a force is needed, allowing for more work to be done with less force. For instance, a ramp can be used to move an object up a height by exerting a smaller force over a longer distance compared to lifting the object straight up.
Overall, simple machines help in reducing the amount of force required, making it easier for a person to do work on an object without needing to exert extra energy.
