"The Speed of Work" Machinery and Human PPT Courseware 2
Description
"The Speed of Work" Machinery and Human PPT Courseware 2
Power: A physical quantity that indicates how quickly an object does work.
1. Definition: Work done per unit time.
2. Expression: Power=work/time P=W/t
3.Unit
SI unit: Watt, symbol W
1 watt = 1 joule/second
Commonly used units: kilowatt (k W)
1 kilowatt = 1000 watts
Note: The symbol of work is W, and the symbol of power unit is W.
Summary
1. Methods to compare work speed:
1. When the work done is the same, the less time it takes, the faster the work is done;
2. When the time is the same, the more work an object does, the faster it does work;
2. To compare how fast an object does work, two factors must be considered:
1. How much work has been done by the object;
2. The time it takes for an object to do work
3. Power is a physical quantity that expresses how quickly an object does work.
1. Definition: How much work an object does per unit time, symbol P
2. Calculation formula: P=W/t
3. The unit is watts, symbol W
