Forms of Energy Energy exists in many forms‚ and when these change‚ energy is conserved. Different forms of energy include the following: Mechanical Thermal Chemical Electrical Electromagnetic Nuclear energy All of these types of energy have the ability to do work‚ which is also the definition of energy. Additionally‚ they have other properties‚ which are specific to their own specific form. Nuclear Energy Nuclear energy is energy in the

Energy conservation refers to reducing energy through using less of an energy service. Energy conservation differs from efficient energy use‚ which refers to using less energy for a constant service. For example‚ driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services‚ it can result in

Energy is an important part of our life‚ and no human being in the 21st century can live without it‚ energy now a day means electricity and electricity is running our world‚ with no energy there will be no electricity and then no hospitals‚ no technology and we will go back to stone ages. Energy sources on planet earth can be classified into two types‚ “renewable” and “nonrenewable” energy sources‚ they both differ in many aspects‚ both of them have advantages and disadvantages‚ and both of them

Solar Energy: Earth’s Future Imagine our planet with clean‚ fresh air. No pollution throughout our whole world. This image is a possibility‚ using solar energy. Solar energy is the harnessing of the sun’s energy and converting it into energy that we can use to accomplish tasks. Everybody should get involved in solar energy because it helps improve our environment‚ is efficient in terms of saving money and time‚ and helps us prepare for the living of future generations. Solar energy is becoming

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic
