Peter Bohacek's lesson and Luke Cahill's animation created this educational video about how work/power....works. What is it? How are these scientific terms related?
Watch it. Learn it. Enjoy it. Share it.
**The video is helpful! TED-Ed uses a clock to explain each concept.
WORK: "the effort exerted on something that will change its energy" (Hewitt 102).
- But that's a bit complicated. Let's say that WORK is just the exertion for force on an object for a certain distance. Work is also a transfer of energy.
- In the video, the clock's metal cylinders were moving up/down; the force applied to the cylinders had to be PARALLEL to the distance at which they were moving. Work cannot be done if the force and the distance are not parallel.
- Work = Force x Distance
POWER: "the amount of work done per time it takes to do it" (Hewitt 103).
- Power has to do with time. The more time it takes to do work on an object, the lower the power. The less time it takes, the more power!
- Work is directly proportional to power; time is inversely proportional to power.
- Power = Work / Time
So the TED-Ed video gives us a better understanding of work and power. I hope this cleared up any confusion that you may have had beforehand. See you later!
CHEERS.
