What is an input force?
What is an output force?

1.) screw, pulley, wheel and axle, inclined plane, wedge, lever

2.)the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour. (joule is J)

3.) The input force (effort) is the amount of effort used to push down on a rod, or pull on a rope in order to move the weight

4.)Output force is the force exerted on an object by a simple machine.

What is a joule and how is it abbreviated?

Abbreviation=J

A measurement of energy and work.

What is an input force?

Input force is the amount of effort used to push down on a road or pull on a rope in order to move the weight.

What is an output force?

output force is the force exerted on an object by a simple machine.

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
