I really like your videos. Many of them are way above my head but I still watch them. You do a great job explaining what's going on and I'm picking up a fair amount of it! Thank you very much for your hard work, it is very appreciated!
Excellent presentation. So many paid educaters make a complete dogs dinner of explaining this! I wish you could write a whole course with problems and answers on physics. It would come to thousands of pages but it would be worth it, as no total self learning course has ever been wriiten.

Thanks, Step by Step Science, for this video. Quick question regarding Watts: Do you know of a conversion formula to convert kilometers/hour to watts in the context of stationary bicycling? I'm an exercise physiologist who exercises patients on a stationary bike that only provides km/h & RPMs as any numerical values to quantify the amount of work they are doing. It has a tension knob for the fly wheel but there is no number value/gauge that's provided for that tension knob. I'm seeking a way to convert the speed (i.e. km/h) into a power unit (i.e. watts) in order to convert it into metabolic units (the unit of workload intensity that we use). Thanks in advance for any information that you may be able to provide!
Oh wow my brother you are an absolute genius and SUPER amazing which leads me to asking you if you would like to help me devoloping a self sustaining energy scourse because i only specialise in coiling and recoiling but totally hopeless at measuring watts that travel through the coils in my modified alternators could really use your help in this department who knows we may be able to change the world some day please reply me or email me when ever you can if you are interest and thank you so0o much for that awesome lesson 👍 You're the BEST ever 👌
Okay, so I have a gas cooker and I have an electric table top cooker (ovens), so what I want to understand is, if I put some product into the gas cooker to cook for say half an hour, and I go to my gas meter and check the reading, and it says I've used 2 units of gas, how can I compare that with cooking the same product in an electric cooker? The point being, how do I work out if a gas cooker is cheaper than an electric cooker? The maths (why do Americans insist upon Math and who started it?) is beyond me, numbers, formulae just don't register in my grey matter (sorry). I do understand that there's a calorific value for gas - natural gas in my case, but I can't see how to equate the two cookers.. or supplies perhaps is better?
Watt is the unit for power and power is the rate at which work is done. A 40 watt light bulb converts 40 joules of electric energy to light and heat every second.
Hello there, I'm new here and I need to ask if have more classes like this here because I need to study physics, math, scientists and more; so if have got, please could you tell me?
Actually, when you're moving upward at 1 m/s², you're acceleration actually 10.81 m/s², because your acceleration will be 1 m/s² greater than the force of gravity already is, so you have to add the acceleration upwards (1 m/s²) to the acceleration which gravity applies (9.81 m/s²) to create the force of gravity, making your acceleration 10.81 m/s². Now, to derive the weight at which a movement upward of 1 meter over 1 second equals 1 Watt of Power, we look at the amount of Joule needed for that, and because it's 1 second, it's 1 Watt divided by 1 Second = 1 Joule. And since Joule is Newton per meter or simple Newton meter (Nm) and we move 1 meter, we can take 1 Joule divided by 1 meter, which is again 1, so we can say we have 1 Newton of force. And since force (in N) is mass (in kg) multiplied by acceleration (in m/s²), we can divide 1 Newton by 10.81 m/s² of acceleration, which equals 0.092507 kg, so the weight should actually be 92.5 grams, to equal 1 Watt of Power when moving the weight 1 meter over 1 second.
So for the pull-up, because you're pulling up 60 cm or 0.6 m in half a second, that means that when you start from 0 m/s, you accelerated to an average speed of 1.2 m/s in half a second, which means your acceleration was 2.4 m/s²; add that to the acceleration that gravity provides, at 9.81 m/s², you'd be accelerating at 12.21 m/s². That times your weight at 95 kg is 1159.95 Newton of force multiplied by the distance at 0.6 m is 695.97 Joule of Work, which you then divide by the time in seconds; 0.5, which equals 1391.94 Watts of Power.
Thanks Google this is the first video in the search for what is a watt. Because this is a brilliant explanation
That's great to know and thanks for the compliment.
i love that you emphasize the formulas. compared to other videos this made the concept easier to understand
Thanks, happy to hear that!
Subscribed after watching this series. Thank you I never understood this when I was at school
Thanks for watching, commenting and subscribing.
Me too

So nice of you. You are very welcome.
Thank you for explaining this! You have a nice voice to listen to also. Keep up the vids 👏
Thank you! Will do, I try to make one video a week.
All 3 videos were super clear... Thank you for doing this for us..!
You're very welcome! Thanks for watching!
Great great vid. Spectacular system on teaching all the units. Thanks so much for taking the time to do this!!!
It's my pleasure to make the videos. Glad you liked them and thanks for your comments.

Wow I never know I used so many power to get a pull up done！ thanks for my dietary advice 😂 haha great video!
Thanks, glad you liked it!
@@stepbystepscience As it always!
you cleared my doubt.sir.Because I am an electrical engineer, this is very useful for me...
Glad to hear that. Thanks for your comment.
You are an angel of physics
So nice of you! Thanks!
We needs more Watts, Gravity, and Joules to support this channel. *wink *wink
That is very funny! Thanks for the comment!
I’m dumb, wt does this mean
finally I understand what is watt
Excellent!

Watt about it
Watt up
Thank you for making these videos.
You are very welcome, thanks for commenting again.
Yes, now I really understand those three, very nice! :)

Good information ji sir
Thanks for helping me study for the test I have at school tomorrow😁😁
You're very welcome and I hope the test goes well!
Good job man.
Thanks!
Thank you so much!!!
Brilliant thank you!
You're very welcome!
Thanks a lot sir
Most welcome
Thanks for reminding me why 50 years ago I flunked school....
This is great thank you! Why do electric companies bill for kw/h?
They charge a certain per kWh.
Cause they charge for energy used not for power.
Thanks for the content 👌🏼
Thanks for watching and commenting.
Good info!!!
Great that you liked it.
ok, ok... i am not even going to ask you Watt did you say...? 🤔 that would be so lame 🤪 great video wish i had these videos in the 60s
Thank you so much
You are very welcome, thanks for watching and commenting
I have a pump of 95 watt if I use 300 inverter what will be the impact of that? Can I use that or not?

Did you round up 1118 to 1120W of power?
Probably.
I like how this guy says watt
Do you have a voltage video?
Of course: th-cam.com/video/f0AQpjh3G9o/w-d-xo.html
and this one has voltage, current and resistance: th-cam.com/video/m75jvmtVyVY/w-d-xo.html
Sir how watt is related to lighting a bulb?
Watt is the unit for power and power is the rate at which work is done. A 40 watt light bulb converts 40 joules of electric energy to light and heat every second.

Watt is named after James Prescott Joule or James Watt?
The joule is named after James Prescott Joule and the watt is named after James Watt.
It's a coincidence that they are both British men named James.
Super sir.
Thanks so much!
Watt can i do with 1.21 gigawatts ?
what is a what
Very funny, I've never heard that joke before.....
Actually, when you're moving upward at 1 m/s², you're acceleration actually 10.81 m/s², because your acceleration will be 1 m/s² greater than the force of gravity already is, so you have to add the acceleration upwards (1 m/s²) to the acceleration which gravity applies (9.81 m/s²) to create the force of gravity, making your acceleration 10.81 m/s². Now, to derive the weight at which a movement upward of 1 meter over 1 second equals 1 Watt of Power, we look at the amount of Joule needed for that, and because it's 1 second, it's 1 Watt divided by 1 Second = 1 Joule. And since Joule is Newton per meter or simple Newton meter (Nm) and we move 1 meter, we can take 1 Joule divided by 1 meter, which is again 1, so we can say we have 1 Newton of force. And since force (in N) is mass (in kg) multiplied by acceleration (in m/s²), we can divide 1 Newton by 10.81 m/s² of acceleration, which equals 0.092507 kg, so the weight should actually be 92.5 grams, to equal 1 Watt of Power when moving the weight 1 meter over 1 second.
So for the pull-up, because you're pulling up 60 cm or 0.6 m in half a second, that means that when you start from 0 m/s, you accelerated to an average speed of 1.2 m/s in half a second, which means your acceleration was 2.4 m/s²; add that to the acceleration that gravity provides, at 9.81 m/s², you'd be accelerating at 12.21 m/s². That times your weight at 95 kg is 1159.95 Newton of force multiplied by the distance at 0.6 m is 695.97 Joule of Work, which you then divide by the time in seconds; 0.5, which equals 1391.94 Watts of Power.
Thanks 🔥
No problem 🔥
75 joules /one second is 75watt or it is like 75 joules per 75second
The first one
Wow! 1 pull-up = 1120 watts? ...If only I could I could power my stereo loudspeakers with my biceps! ;)
You must be very powerful.
My English listening and understanding is weak, how do I can understand your lecture sir? ☹️
You can slow down and replay the videos. Good luck!
subbed of course after that. been buying batteries ;-)
Thank you very much.
watt is a watt
Very funny, I've never heard that one before.
@@stepbystepscience haha
because what accelerates a car in all revs is power not torque like most people belive
So... watt is a what...?
say the title 10 times fast
1 joule per second
yes.
100 grams ? i thought it was 1 kilogram = 1,000 grams ... 1 meter in one second.
explanation was not that clear
what is a watt
whatt
Can't you properly.sorry but what are you speaking is not clear.
550 watt
