    Does Cold air cause more Air Resistance?

    Gfg Ok, if it was a bicycle? There will only be more air resistance facing the bicycle without producing more power like you said previously about the combustion engines, because of course the bicycle doesn't have an engine... Am I right? Please answer me and thank you guys for answering you...

    Does Cold air cause more Air Resistance?

    I know that Cold Air is more dense than the warm air, so for example: If a car was accelerating facing a hot air, it will face less air resistance. But if it was facing a Cold air, it will face more air resistance because the cold air contain more mass per volume for each particle. It will face...

    Universal Gravitation Constant - HELP

    Universal Gravitation Constant - HELP! Hello, I'm a little confused... What is the difference between the "Constant of Universal Gravitation" and the "Gravitational Force"? I know that there is a radius between two or more objects like the Earth and the Moon and bla bla bla... But the thing...

    How does a dynamo produce electricity?

    And Electric-Powered Vehicles don't have fuel so there's no big reaction is happening to transfer the Mechanical Energy to the dynamo to power the engine. I think that's it...

    How does a dynamo produce electricity?

    Sorry for asking too much, you know that Dirt bikes (internal combustion engine) which have a "kick starter" start engine without batteries. And cars (internal combustion engine) usually have batteries. So... What's the job of "Fuel" or "Petroleum" in cars? I'm really curious and interested to...

    How does a dynamo produce electricity?

    Hello, thanks for your informative beneficial answer! But I wonder do "fully Electric-powered Vehicles" have dynamos to charge their batteries? And if they do, there will be no more wall-charging?? Or it will only charge for only some miles/kilometers? Waiting for your answer as soon as...

    Are Free-Energy Dynamos Real or Just a Myth?

    I really wonder if there was because I watch on youtube videos about free-energy generators/dynamos. If there was why wouldn't we use it for houses and power plants?? Or it doesn't produce much power? Thanks!

    Dynamos & Power Plants - Question

    Then why do we use Oil and Nuclear Reactants for power plants to produce electricity? It was said that the "Oil has to be burnt to boil water and make steam, use the steam to drive a steam turbine, use the steam turbine to spin the electrical generator/dynamo to make electricity." And the...

    Dynamos & Power Plants - Question

    Dynamos & Power Plants -- Question Please Read! I know that cars need batteries to generate electricity to the dynamo to make the dynamo produce electricity continuously without stopping unless you switched off the car. The same to motorcycles. But I don't know whether the power plants do the...

    How does a dynamo produce electricity?

    *** And does a dynamo in a power plant works without batteries? If so why? Why does a dynamo in PP works without batteries and cars do? Sorry for asking too much but you really make me understand how dynamos are working. Thanks!

    How does a dynamo produce electricity?

    Or the Oil and other resources like Nuclear reactors are used instead of batteries in Power plants?

    How does a dynamo produce electricity?

    You mean by "smooth out any voltage" is to prevent dangerous voltages coming out from the output of a dynamo? Ok, but how will it not work without a battery? The Dirt bikes already work without batteries if they had a "kick starter" that start the dynamo with mechanical energy as I think...

    How does a dynamo produce electricity?

    Q: When the dynamo is switched on, it produces electricity automatically without the need of a battery? Because I recently saw some videos of people manually produce electricity by dynamos via their Kinetic Energy. So what's the difference? Thanks!
