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.
What is A simple machine that consists of a flat surface with one end higher than the other ramp?
A ramp is a simple machine that allows for easier movement of objects from a lower to a higher surface by reducing the amount of force needed. It works by increasing the distance over which a force is applied, making it easier to lift objects against gravity.
What increases the work output of a simple machine?
Increasing the input force or the distance over which the force is applied can increase the work output of a simple machine. Reducing friction within the machine can also help to increase its efficiency and work output.
In a machine the effort force you apply is used to overcome a?
In a machine, the effort force you apply is used to overcome a resistance force, such as the force of friction, gravity, or inertia. The goal of the machine is to make it easier for you to move or lift objects by increasing efficiency or changing the direction of the force applied.
Reducing friction increases the ideal mechanical advantage of a machine?
Reducing friction helps to minimize energy loss, making the machine more efficient. This allows the machine to transfer more of its input force or energy into useful work, increasing its ideal mechanical advantage.
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.
One way a machine can make work easier is by?
reducing the amount of physical effort required by amplifying or transferring the force applied by a person.
What kind of simple machine is an inclined plane around a cylinder?
An inclined plane around a cylinder is a form of a screw, which is a simple machine. It works by reducing the force needed to raise or lower an object by increasing the distance over which the force is applied.
What happens when a machine changes the size of the force?
When a machine changes the size of the force, it can either amplify or reduce the force applied to the object. This allows the machine to perform work more efficiently by either increasing the output force (mechanical advantage) or reducing the effort required to move the object.
What do you get when you divide output work by input force?
When you divide output work by input force, you get mechanical advantage, which is a measure of the factor by which a machine amplifies the input force to perform work. It can also tell you how much easier a machine makes a particular task by reducing the amount of force needed.
