Energy Smart

shreyash asked:


I’m asked to do a simple project on Electrical energy conservation … the easy and simple steps that one can take in day-to-day life etc. I searched it out on wikipedia and couple of sites, but didn’t get enough info.
I’d be glad if someone could help me out in this.

The focus must be on a specific problem within this topic. Does anyone have any good ideas? Thank you.

If everyone in america reduced their fuel use by 30% annually, would that make a difference?
I wish the Big 3 would re-release a simple, all-manual, no-frills 4-banger pickup with a 5-speed manual trans. Heavy springs and stiff frame/good brakes give you payload carrying capacity, the 4-banger and the 5-speed gearset give you an economical way to move it from A to B. Buuuut, all the shitboxes they’ve sold as ‘pickups’ for the last 10 years all have an insanely high GVW, fuel-swilling engines, and every option known to man including some that only belong on the shuttle. Over-marketed crap still doesn’t get to the zone of real economical operation, there’s trade-offs in life, I can’t wait until Mazda or somebody builds such a truck in the US and makes it run on hydrogen(which can be made, like, at the coast, for relatively cheap, truth be known). But, the Big 3 will change…in a pig’s ass, maybe…shoes are still 100% energy-efficient…

Pythagor asked:


Hello,

I have got a problem which is described below.

A heavy metal ball starts to fall from 1 meter height, ant this ball hits a light tennis-ball on the table. After the hit, metall ball rises nearly to 1 meter height. To what height does a light tennis-ball rise?

In my opinion, energy conservation law should be used here. But then it means that the tennis-ball nearly don’t rise, and as I suppose, it is not a logical answer.

Could anyone help me with this problem?

Thanks in advance.
This is a problem where masses can’t be measured.

That is, initially the rock has a high potential energy. Then, its energy is converted into kinetic energy as it falls. So i understand energy is merely changing form.

But then it hits the ground. The rock ceases moving at a relative height of zero. Into what form was the enrgy converted? Is it converted into kinetic enrgy that travels through the particles of the ground? Thanks a lot!

Use the conservation of energy and momentum to show that pair annihilation CANNOT produce only on photon.

~Fefi~ asked:


How are the laws of conservation of momentum and energy similar?

Here are the formulas:

Law of conservation of momentum:

P1 + P2= P1′ P2′

m1 v2 + m2 v2 = m1′ v1′ + m2′ v2′

Law of conservation of Energy:

KEi + PEi = KEf + PEf
I think that the energy can’t be created nor distroyed but it can be transformed from one form to another.
But is that the similarity???
