Work and Machines. What is a machine? A device that allows you to do work in a way that is easier and more effective.
Section 5-2.  The work done by a machine is work output. Work output = resistance force x resistance distance.  The work done on a machine is work input.
Work done is the energy transferred when a force moves an object over a distance. Since work is energy transferred, the unit for work is the joule (J).

Presentation transcript:

Work & Power

Work Work is defined as

Power Power is defined as

Mechanical Advantage Mechanical Advantage is defined as

Efficiency Efficiency is defined as

How do machines make work easier? Machines make work easier by

How do machines lose efficiency? Machines lose efficiency because of the friction that comes from the parts rubbing on each other. When this happens it causes the thermal energy to be lost and makes the machines break down and lose efficiency

How does this effect us everyday? What does this mean for us?
