- 15.1Energy around you.
- 2Just a kind information...nvm, u will realize later....
- 3What is energy?Energy is the driving force for the universe.
- 45 Different forms of energy1. KInetic
2. Light
3. Sound
4. Heat
5. Electric - 5Kinetic EnergyThe energy of movement.
- 6Light EnergyEnergy that comes from the sun, light globes, flames etc. Tt is the only form of energy that we can actually see directly
- 7Heat EnergyEnergy that we get through sun, fire etc.
- 8Sound EnergyEnergy that air has when it vibrates.
- 9Electric EnergyEnergy that is produced by power stations, solar cells, batteries etc.
- 10Potential EnergyThe energy that is stored
- 11Examplesbattery, stretched rubber band, petrol in car's tank, books on a shelf and much more.
- 124 different types of potential energy.1. Elastic Potential Energy
2. Gravitational Potential Energy
3. Chemical Potential Energy
4. Nuclear potential energy - 13Elastic Potential EnergyThe energy that is stored as a result of deformation of an elastic object, such as the stretching of a spring.
- 14Gravitational Potential EnergyThe energy an object has due to its position in a gravitational field.
- 15Chemical Potential EnergyThe energy stored in chemical bonds. Gasoline and the food that you eat are examples.
- 16Nuclear potential energyenergy stored in the nuclei of an atom. Nuclear fusion is the released energy through the combining of nuclei. Nuclear fission is the release energy through the splitting of a nucleus.
- 17Energy transferEnergy can be transferred from one object to another
- 183 ways can energy be transferred1. Conduction
2. Convection
3. Radiation - 19Conductionthe process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
- 20Convectionthe movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
- 21Radiationthe emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
