Energy
The Energy category covers the description, definition, and use of all types of energy. Questions of a general nature can be put in the general Energy category. Other sub-categories exist for Fossil fuels, Nuclear energy, and renewables such as Wind, Solar, Hydro, Tidal, and Wave power.

All the ways energy is used in home?
Asked by Wiki User
Energy can be used for cooking and heating up water. It can be used for lighting and electrical appliances as well, such as televisions, fans etc. In some ways, anything involving the switching on of a switch can be said to use energy.
What was Hans christian oeresteds hypothesis on electric current flows?
Asked by Wiki User
a magnet...!
What is the greatest velocity a fallingobject reaches?
Asked by Wiki User
It's called terminal velocity and it's when the downward force of gravity equals the upward force of drag due to air resistance.
What are the Future energy sources used to produce electricity?
Asked by Wiki User
Wind and solar power .
Do cars use energy?
Asked by Wiki User
Yes. A car converts the chemical energy in gasoline to kinetic energy of motion.
More than 65% of the energy in the gasoline is wasted, and never becomes kinetic energy.
How is kinectic and ppotential energy different?
Asked by Wiki User
In the world of science we do not understand many ungodly things you my friend need to listen...
Kinetic energy is a source of a moving energy; like a ball rolling or you throwing a pen using force (also known as work)
Potential energy as we call it is stored energy like a ball NOT rolling just sitting there.
so kinetic is moving energy and potential is non moving or stored energy!
Wow!!
HEY THAT IS COOL!!! SAY THAT RIGHT NOW!
made by a genius in her fifth grade lab!
if you are an older person (passed collage) then you would lose "Are you smarter than a fifth grader" because I am!!!
you bonk, you snarky gadzook, you homosapien... ha ha those words all mean human!!!!
Can nonmechanical energy be converted into mechanical energy?
Asked by Wiki User
Heaven's yes.
Food (chemical) becomes muscular activity.
A battery (chemical) runs a little fan.
A motor (driven by electrical) runs a big fan.
Fuel rods in the power plant (nuclear) boil water (heat) which turns a turbine (mechanical) which runs a generator (mechanical to electrical) which runs everything (back to mechanical).
What happens to the particles in objects during conduction?
Asked by Wiki User
When a body is conducting, its mobility of ions( valence) is responsible for conduction. As mobility increase, conduction increase. That's why falling temperature reduce it and rising temperature increase it.
Name two other materials that are poor conductors of electricity and might make good insulators?
Asked by Wiki User
plastic, glass and rubber
What tropic level contains the greatest biomass in most ecosystems?
Asked by Wiki User
trophic level one.... the tertiary consumers, or top carnivores
What are two things that respond to change and use energy but are not living?
Asked by Wiki User
tech plates and the autmassphere
What force is path-dependent and will change an object's total mechanical energy?
Asked by Wiki User
nonconservative
What is the excessive use of conventional energy?
Asked by Wiki User
energy can be in forms of heat light and sun as well as energy resources like electricity,gas,power,water and etc. if these energy resources are used excessively it will have greater effect on man,s life and routine.
Energy transformations for a falling parachute?
Asked by Wiki User
a falling parachute, energy before would be gravitation and energy after would be movement.
Why have attempts to create a perfectly energy efficient machine been unsuccessful?
Asked by Wiki User
The input energy can never equal the energy outputted by any machine because energy is always lost in the process. Where that energy is lost is dependent on the machine, but some easy examples would be heat (namely due to friction), sound, and radiant (light).
Can energy be transformed into matter and vice-versa?
Asked by Wiki User
Once the mass is known, so is the energy, and vice versa. So yes it can be transformed both ways.
