Work equals force times distance. In reality, you don't decrease the force by the same proportion that you increase the distance because of friction. In English, you need less power (work per unit of time) to complete the task, but it takes more work (energy) because of more distance of friction.

Machines make work easier by reducing force and increasing what?
A machine makes work easier by reducing force and increasing distance.
How does a crowbar make work easier?
it makes work easier by changing an input force into a larger output force.
How do simple machines do work?
They use the aerodynamics of the perpetual motion machines to produce an inverse relationship which allows the input force and effort to be reduced, thereby increasing the distance over which the object is obliged to TRAVEL.
3 ways simple machines make work easier?
Machines make work easier by: -Changing the amount of force you exert -Changing the distance in which you exert your force -Changing the direction in which you exert your force
Do simple machines reduce the amount of work?
By simple machines, I assume you mean machines powered by muscle but using leverage such as levers, screws, block and tackle devices. Is that what you mean? If so, these devices increase something called "mechanical advantage". Start with levers. The usefulness of a lever depends on where the fulcrum is placed. If the fulcrum is in the centre of a lever such as with a see-saw, there is no mechanical advantage at either end. That's why kids of similar weights can suspend the kid on the other end of the see-saw up in the air just to be rascals. Now if the fulcrum is closer to one end than to the other, the person farther from the fulcrum can exert more force than the person closer to the fulcrum. Think of a crow bar. One inserts an inch or two of the bar at the point where one wants to apply force. Pushing on the other end of the bar (perhaps two, three, four feet away) exerts a lot of force at the other end. The same effect allows you to lift a car with a jack. You push down a foot on the jack handle and the jack platform rises perhaps half an inch.
Machines make work easier by reducing force and increasing what?
A machine makes work easier by reducing force and increasing distance.
A machine makes work easier by reducing force and increasing what?
By increasing productivity and reducing the force, a machine makes work easier. They also last longer than people and do not require pay.
What machine makes work easier by reducing force and incerasing?
I think you may be thinking of a lever.
How changing direction of force makes work easier?
A simple machine makes work easier by reducing the force which it takes to move something. Also it makes life eaiser, but taking shortcuts does not always help.
Which simple machines rely on changes in direction to make work easier?
An axel is a simple machine that relies on change in direction to make work easier. Furthermore, a simple machine is a device that makes work easier by increasing force or changing the direction of a force without electricity or other power sources.
What simple machine has a rope over a wheel?
A tire is a wheel and axle. This simple machine makes work easier by reducing the amount of force that needs to be applied to move a load.It is an Wheel and axle.
How does a rake act as a machine by which the force is applied?
Decreasing the applied force and increasing the distance
How lubericating a machine affects the output force exerted by the machine?
It maximizes it, by reducing the internal losses to friction.
How does a simple machine decrease the input force required?
by increasing the distance.
