You're not quite sure of the difference, are you ! ? Come on, tell old Al the truth.
The power output of a car's engine changes, depending on how much you need
at the moment. That's why you have a control on the floor and you keep your
foot on it, so you can make large or small adjustments in the engine power quickly.
I don't know much about cars, but I think I've heard somewhere about a car
with a "300 horsepower" engine. That would be the maximum power that the
engine is capable of, when you push the power-control to the metal and rev
that baby up to screaming.
300 horsepower means 223,800 watts (223.8 kilowatts) of power.
When it's running at that level, it's delivering 223,800 joules of energy every second.
You know how your electric bill shows how many "kilowatt-hours" of electrical energy
you used last month, and that's how many you pay for ? Kilowatt-hours of electric energy
cost anywhere between 5¢ and 30¢ each, and maybe you use a few hundred of them
in your house in a month.
Well, if your engine is screaming and you're burning rubber and you're flying down the
strip and everybody else is eating your dust and you're turning 300 horsepower, then
your engine is delivering a kilowatt-hour of energy every 16 seconds.
How big around are the pistons? What's the stroke of the engine? How fast is the engine going to be run? All of these things (and more) will determine an engine's horsepower rating. That rating can then be converted into watts.
The "units" are called joules (J), not to be impolite. The answer would be about 19.9809 J.
(Air and rolling resistance ignored)Power required = energy change / time taken>Problem:Power required to accelerate 1000 kg car from 0 to 60 mph ( 26.82 metres / second) in 3 seconds ?>kinetic energy gained (energy change)= 0.5 * mass * velocity2,>so 0.5 * 1000 * 26.822 = 359656.2 joules>Power required = energy change / time taken= 359656.2 / 3= 119885.4 joules / second (watts)= 119.8854 kw (about 161 bhp)
3500W, or 3.5kW Power is measured in Watts; one Watt is 1 joule of energy converted/used per second. So, 3500 joules a second is 3500 Watts.
About 208,796 watts.
About 298,400 watts.
About 171,511 watts.
Depends on the car.
The Legacy Car Audio LBP22 is 1200 watts.
about 100to 150
watts equals volts times amps,do the math
Ignition 30 watts, fans 30 watts, driving lights 30 watts, headlights 100 watts. Total about 200 watts.
they use around about 55 watts for each headlight.
None. Solar-powered cars are based on sun-ray and not watts.
