Positive and Negative Charge

In this video Paul Andersen explains how all objects contain positive and negative charge. Neutral objects contain an equal amount of positive and negative charges. Charged objects have more positive or negative charges. Like charges repel and unlike charges attract. Neutral objects can be polarized and cause attraction.

Important to note here that there is no such thing as 'more positives' it is actually 'less negatives' that make something positively charged. Protons can't move from the nucleus of an atom!
-
finally I understood this concept after 17 years
-
I got so confused when I was learning circuit boards because I always thought the energy went in through the positive of a battery and out through the negative so this helped me finally understand they both output energy. Thanks for the great video. Can't believe it's 14 years old

How can you purposefully charge an object with a negative charge, and how would you store that negative charge?
-
plz make as much videos on science subject as u can..because your videos r really helpful.i can only understand if someone explains patiently .thankyou Mr.Andreson😊
-
But what is positive and negative what does they mean, and why do opposite charges attract in the forst place.
-
really helpful in making the concepts more strong!!!!!! thanks alot!!
-
These physics videos have quite clear graphics and they are fun too. They might be great for learning English as a foreign language especially for people who love science more than languages. Sth like extras for English teachers at schools abroad, ideally with some simple added revision questions both for physics and vocabulary.

I still have a slight doubt to as: 'if the negative charges are transferred from the sweater to the balloon - and in theory negative charges should repel - why was there a bunch of negative charges all clustered up together in the balloon?' Or does the principle not apply to the charges in the balloon? Can someone help explain this to me please? Thank you so much!
-
very confused on how charges move. For instance, on the simulator, why can't the balloon take electrons from the wall? Would that simulator only work with balloons or would any object be able to take electrons away by rubbing? For instance, could I have just rubbed my hand on a sweater or a box and obtain a negatively charged hand?
-
So negetive charge needs the positive charge and it goes near it?
-
Thank you so much for this informative video
-
So what are positive and negative charges other than the equal and opposite forces had by electrons and protons? Do they have shape or pattern to the mechanics that make a charge one or the other?
-
If the balloon never touches the sweater, after being charged. How does the sweater get its' electrons back? Does it remain positive charge? thank you.
-
What happens if you rub two ballons, and put them together at the area where the electrons are more and let them go at the same time. Will they go away from each other or stick?
-
Amazing video, helped so much. Thanks a lot
-
You helped a lot, thank you very much!
-
hi hope all is well, can you please tell me if it is possible to permanently make a metal surface negatively charged?
-
Thank you sir,that helped me a lot.
-
Thanks for knowledge .
