Mechanical advantage, Efficiency and WO WI Simple machines.
Chapter 5 Work, Energy and Power. Section 5.1 Work Work - The quantity of force times distance, as long as the force is parallel to the direction of motion.
Simple Machines In a simple machine, input work is done by a person applying a single force, and the machine does output work also by means of a single.

MACHINES – UNIT 5. DEFINITION OF MACHINE ANY DEVICE THAT HELPS PEOPLE DO WORK. IT DOES NOT CHANGE THE AMOUNT OF WORK DONE.
Work and Machines What is a machine??. Machines: making work easier Think about changing a tire- what tools do you all need? Think about the amount.
Physics Review Day 2. Energy Energy is conserved in a system, it can not be created or destroyed Energy is simply defined as Work There are two types:

Mechanical Advantage and Simple Machines. Work Input and Output A machine is anything that transforms energy –Work Input: the work/energy supplied to.
Efficiency is a level of performance that describes a process that uses the lowest amount of inputs to create the greatest amount of inputs. 2.
