A definition of energy is the ability to do work. When work is done, energy is used. So the effect of energy is to enable things to get done: this could be to power a vehicle or airplane, to heat a...
Think of an object falling from a cliff: Potential energy = mass x gravity x height. So a larger object falling from a higher cliff will start out with more potential energy. As it falls, it speeds...
Solar panels are not as efficient as they could be -- one of the reasons why they have not been widely implemented yet. To capture appreciable amounts of energy, they require a large number of cells,...
Kinetic Energy is theproperty it can not effect anything. It tells how big amount of energy is stored by the object just because its moving. Or in the other words, what amount of energy was given to...
