Many tasks require you to do a certain amount of work. But the same amount of work can be done in a short period of time or over a longer period of time. Power describes how fast work is done. Power is the rate at which work is done. This video explains everything you need to know about what power is in physics and how to calculate the power exerted. Five different example problems will show you how to calculate the power output, the amount of work done and the time it take for a given power output. Everything is explained step by step.

I'm extremely new to physics. I appreciate the work you and whoever else put into these videos. We all need education, for sure. With that being said, you ramble very fast and at times it's hard to "catch up" while understanding the concepts presented. Maybe it's just the way you speak, or there could be a simple solution like less caffeine or taking some wholesome breaths before recording. Also, the capitalizations are confusing when you use a W for watts when the focus for the video is on W(work). In one example, you used a lowercase s for seconds, yet used an uppercase W for watts, when the focus for the W, in my opinion, should only be used for the formula you are presenting, part of that being W= Work. The animations are helpful, and I thank you for your time 🌟

Sorry if I am going too fast, it is always a balance between fast enough to keep people's attentions and too fast that people can not keep up. As far as the units and symbols go...The abbreviation to work is W and the abbreviation for watt is also a capital W, but each is spelled in a sentence with a lower case w. Those are the rules and I can not change them. Thanks for your comments on the video.
