A broom is an example of a machine. where are the input and output forces applied?
The applied force to the end of the handle is the input force and the output force is when the broom sweeps over the floor.
Can a machine increase both the force and the distance over which the force is applied Why or why not?
No. That would violate Conservation of Energy.
Why are levers useful?
A lever is a simple machine that changes the distance the force is applied over. It is helpful by since the force is applied over distance you can lift things. One example of this machine is a seesaw and a boat paddle. If we did not have this machine on a seesaw we would stay balance. Levers are devices that increase the force you use them with. Each lever has three main parts: the fulcrum, resistance arm, and effort arm.
How does machine change direction?
It changes the size of the force and the distance over which the force is applied.
Does an inclined plane decrease the applied force and increase the distance over which the force is applied?
Yes, your right.
How do you compute input work of a simple machine?
You multiple a force time the distance over which the force is applied.

When a simple machine is used to perform a task what factors may be affected?
the amount of force needed to perform the task the distance over which the force is applied the direction in which the force is applied
When a simple machine is used to perform a task factors may be affected?
the amount of force needed to perform the task the distance over which the force is applied the direction in which the force is applied
Who is greater the applied force or the force exerted by the machine?
That depends on whether the machine is designed to multiply force or distance. A machine designed to multiply distance will exert less force than was applied, and a machine designed to multiply force will exert the greater force over a shorter distance than force was applied to it. As for work, output work is always less than input work because some energy is lost in overcoming friction.

What kind of simple machine is a boat ore?
Sailing boats are full of ingenious examples of pulleys; rowing boat oars provide one of a few examples where the fulcrum is located such that it reduces the applied force and increase the distance over which it acts
When the area over which a force is applied decreases what increases?
When the area over which a force is applied decreases, the average force applied over said area increases. In other words, the pressure (force/area) increases.
Force is applied to an object and the object is moved over a distance in the same direction of the applied force is the definition of?
Work is applied to an object and the object is moved over a distance in the same direction of the applied force.
