Work, Energy, and Power: Crash Course Physics #9

Spread The Viralist



When you hear the word, “Work,” what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics and today, Shini is going to walk us through it. Also, Energy and Power!

  1. I’m watching this video for my online summer school and I hate it the adhd is real Nd her big words don’t intrigue my little mind 😂😂 (British stuff British stuff British stuff (imagine saying that in a British accent))🤣🤣 (you lost me at velocity and per sec (if anyone sees my comment and would like to dumb it down for me I’d appreciate it)) 😭🤦🏾‍♀️

  2. Your videos are really helpful for reviewing some of the important concepts a day or two before an exam. Trust me if I would've watched this video without learning the chapter at a slower pace in school I would definitely feel lost😂😂. But thanks to your videos I've developed a lot more confidence than before. You are great teacher.THANK YOU

  3. This YouTube channel literally help me in every school assignment no matter what I choose. Whether it’s history or science I always find the answer

  4. I dont understand the difference between power and force? Force is defined as the interaction that will change an object's motion (accelerate it). So this means it has to move. So if you were to pull the box with 100000000N (net force) but at 0ms, then WTF does that mean? It will accelerate but not move at the same time?

  5. power is the rate at which conservation of energy takes place like example the time taken when mechanical energy transforms into electrical energy in a dam where the continuous water flow triggers the turbine to basically rotate which we also call magnetic induction where the turbine magnetized and so the electricity can be formed because of the laws of electromagnetism

  6. why your HD video quality isn't HD? It looks like the video is running on 480 pixels even it's on HD quality. I think you need a better cameraman and editor for your videos. otherwise, your teaching is great!

  7. What happens when you spend energy and power, and produce no work – for example you try to life weights but cannot lift it one inch given all the power and energy you have. What happened to the energy and power spent?
