Is there any damage to the environment with energy used if so what?
yes! if we use 2 much energy we will lose energy. u get me err
A bicycle rider notices he is approaching a hill Explain in terms of energy why the bicyclist pedals hard to gain as much speed as possible on level road before reaching the hill?
By going faster the cyclist is storing up kinetic energy which he can spend in rising the hill. If lucky there will be no struggling with the pedals grinding up the hill, and might even coast over it. Without this energy pre-storage, the cyclist would have to provide energy at a rate fast enough to prevent him slowing down too much and falling off and the cyclist might not be capable of this (rate of supply of energy = power).
What does kind of energy does a skier traveling downhill have?
Half way down the slope, the skier has kinetic energy and potential energy. At the top of the slope, before he starts moving, he only has potential energy. At the bottom of the slope, he has only kinetic energy. This is an extremely simplified explanation, but it's probably the answer that your teacher is looking for. Hope that helps.
Do electrons lose energy or speed when they cross over a resistor?
You won't like the answer....but electrons are charge carriers and neither their speed nor their energy has much to do with what happens within an electric circuit.

How does a roller coater changes speed?
as the rollar coaster goes up the "hill" as far as it can go , it is considered. Once there it goes down hill and becomes kinetic energy. The roller coaster changes speeds because of the series of hills it goes up and falls down. At the top of the first lift hill (a), there is maximum potential energy because the train is as high as it gets. As the train starts down the hill, this potential energy is converted into kinetic energy -- the train speeds up. At the bottom of the hill (b), there is maximum kinetic energy and little potential energy. The kinetic energy propels the train up the second hill (c), building up the potential-energy level. As the train enters the loop-the-loop (d), it has a lot of kinetic energy and not much potential energy. The potential-energy level builds as the train speeds to the top of the loop (e), but it is soon converted back to kinetic energy as the train leaves the loop.
How much energy you need to lost 1 calorie?
A calorie is a measure of energy. It doesn't make sense to ask how much energy you need to lose energy.
How much energy does it take to breed on Howrse?
Both mare and stud will lose 25% energy when breeding.
How much energy does it take to lose a lb?
3500 Calories.....A Calorie is simply a measurement of energy expenditure
How much more gravitational potential energy does a roller coaster have at the top of a 72m hill and has a mass of 96.6kg?
The coaster has more gravitational potential energy at the top than it has at thebottom. The difference isM G (h2 - h1) = (96.6) x (9.8) x (the distance between the top of the hill and the bottom of the hill)If that "72m" is actually the distance between the top and the bottom of the hill,then the coaster has 68,210 joules more PE at the top than it has at the bottom.If it doesn't lose any of it to friction on the way down, then that entire juicy 68,210 Jis available to be turned into kinetic energy on the way down. How fast could it begoing when it gets to the bottom of the hill ?KE = 1/2 M V2 = 68,2101/2 M = 48.3 kgDivide each side of the KE equation by 48.3 :V2 = 1,412.2 (m/s)2V = 37.58 meters/secondThat's 84 miles per hour !Note:You didn't say anything about the mass of the people in the coaster car,or even whether there's anybody in it. If there are riders in the car, thentheir mass naturally adds to the mass of the car. The chain has to do morework to drag it up the hill, it has more gravitational PE when it gets there,and it's moving faster when it returns to the bottom.
If a roller coaster has 100 joules of energy at the top of the first hill how much energy will it have at the bottom?
100. The amount of energy a roller coaster has is maintained throughout the whole journey. Its the conservation of energy - energy can' t be created or destroyed it can only be transferred. It therefore depends what type of energy you mean in the question. It can have a total of 100 joules meaning yes, anywhere on the roller coaster it will remain as 100 joules however if your saying 100 joules of gravitational potential energy at the top by the bottom of the hill it will have decreased and have been converted into at least 80 joules of kinetic energy leaving 20 joules as gravitational potential energy. Sorry for the poor grammar; just focus on the science. I have an exam on this in two weeks...
Is it better to go up hills or down them when exercising?
Up hill. It builds energy, and strenth. Going down hill doesnt do much

How much should you ride your bike to lose 1 pound?
it depends on how fast you ride or if your gowing up a hill
What happens to the particles of a liquid as the lose more and more energy?
they dont move as much
How much energy does iodine need to lose an electron?
1008.4 kJ mol-1
Do mouse lose there antlers in the winter?
Yes because they have to use extra energy to use them. If they lose their antlers, the energy that is usually used to grow them can be used to survive without much food in the winter.
