Friction force oppose motion between two bodies that are in contact. This force is important in machines and pulley systems in that it enables the gears to have grip and there is no unnecessary sliding.

Describe how simple machines make work easier?
Simply put, a simple machine makes the work much easier. Simple machines reduce the amount of force needed to do the work. A pulley, for instance, is a great example of a simple machine.
How can simple machines a simple machines?
A CATAPULT IS A LEVER!!!
Do all simple machines either reduce the input force or increase the distance over which work is performed?
Simple machines will reduce the input force, but can allow you to travel farther distances. Your'e body is not putting in as much force, your body will allow you to do more work for a longer time....but yes,it decreases the input force.
Does using machines reduce the total amount of work required to move an object or make it easier?
Yes. Use simple and compound machines always get things done faster and better.
How many simple machines are needed to make a compound machines?
6 simple machines.
Why it is important for you to reduce friction on compound machine?
Because too much friction can damage the simple machines that make up the compound machine.
How do simple machines make work about the same?
They do not. Simple machines reduce the effort used to do a task.
Why do levers have a greater mechanical efficiency than simple machines?
The transmission lever is very simple and there is no friction.
What does simple machines change?
Simple machines such as pulleys, wedges, and levers reduce the amount of energy required to lift or move (heavy) objects.
Is the pen a simple machine?
No. The classic simple machines are: Lever Wheel and axle Pulley Inclined plane Wedge Screw Using the pen has no mechanical advantage, other than in a ballpoint pen where the roller bearing reduces friction, but is primarily intended to produce an even ink application.
Levers have a greater mechanical efficiency that other simple machines because?
They have to overcome less friction

How does friction affect perpetual motion machines?
IN SIMPLE WORDS: Friction turns mechanical energy into heat energy which causes a loss in mechanical energy and loss in possibility to continue motion..
What simple machine reduces friction?
If I'm not mistaken, there is no machine that can reduce friction. The machine is intended to change the distance the input force is applied over or to multiply the output force. The moving parts of the machine will always increase friction. In order to reduce the extra friction (but not completely remove it), one would use a lubricant or reduce the roughness between two surfaces. Hope it helps.

Do machines use power to perform work in a more energy efficient manner?
Yes, a simple machine can create friction, and friction can create heat. You are converting mechanical energy to thermal energy.
Does the simple machine reduce overall work needed?
No. Work out is always less than work in due to friction and other losses..
