Want this question answered?
potential energy or static electricity.... when you hold an object in the air, you are storing energy inside the object because of the pull of gravity. this is called potential energy a charge in an object is static electricity, which is also stored energy
Because the molecules are less dense and they vibrate faster letting sound travel faster
Potential energy is a stored energy due to the gravity and height above the ground. In physics the formula for potential energy is: PE = mgy where m = mass (kg), g = acceleration due to gravity (m/s^2), y = height (m) What if there is no height? Well, by simply letting y = 0 and multiplying 0 to m and g, we get PE = 0. Therefore potential energy does not exist and shows it is only present when the object has a height above the ground.
no In most all cases, yes. You use kinetic energy (energy due to motion) if you move, or if you move something. The most common form of potential energy is gravitational potential energy (basically energy due to height). You use this if you fall down (or fall into your bed) or if you drop something (even if it's dropping your backpack from two inches off the ground). You use gravitational potential energy when you drink from a cup by letting gravity do the work of moving the liquid down. It can also be argued that chemical energy is potential energy, in which case, you use it when you eat and obtain energy from food.
because it looses energy in the process (to the ground, environment) therefore not letting it permit to bounce as high as it previously did.
kinetic
kinetic
Burning fossil fuels turns potential energy into kinetic energy. Kinetic energy is energy in motion, which can be used to do work.
well its both because...it's a chemical change because when the tree is burning it's letting oxygen and carbon oxide in the air. It's also a physical change because if that tree is sharing roots with another tree that other tree root will become damaged and will sooner or later will be dry rotted and the tree will fall over(it can also damage the grass around it).
Scientists are burning down the rainforests and letting off nukes.
There letting water out of the Mississippi because so then it wont flood as much as it has been.
Because nobody needs a car.The simplest thing to do is get a bike or something that doesn't use fuel because all the gas coming out of your car goes up into the Atmosphere burning holes through it letting more of the sun's harmful rays shine down on us.
It is because it is under construction.
Letting another man die in the draft dodgers place is not morally justified.
We can stop burning methane. Actually burning methane is better than letting it escape into the atmosphere. Methane, when burnt, emits carbon dioxide, a powerful greenhouse gas, but methane, when released into the air, is twenty-one times more dangerous.
providing is giving to or letting someone have...an letting them us it because thay dont have it with them orr dont have it at all..... by shaneka
The reason ehy sketchfu is not letting you sign p is because there are way to many people on sketchfu.
