How is kinetic energy created?
It’s created only after potential energy is released, typically by gravity or elastic forces. When more potential energy is released, more work is done and the object in question begins to accelerate, which increases kinetic energy.
Where does energy gained from gravitational potential come from?
Though gravitational and elastic potential energy are different, in both forms energy gained comes from the potential energy that was stored in the objects before being knocked out of equilibrium. The difference is in whether they were knocked out of this by elastic rebound or gravity.

How does coal affect the environment?
The air and water pollution emitted by coal and natural gas plants is linked with breathing problems , neurological damage, heart attacks, cancer, premature death, and a host of other serious problems. The pollution affects everyone: one Harvard University study estimated the life cycle costs and public health effects of coal to be an estimated $74.6 billion every year. That’s equivalent to 4.36 cents per kilowatt-hour of electricity produced—about one-third of the average electricity rate for a typical US home [ 6 ].
Do geothermal power plants need water?
