This includes atoms and anything made up of these, but not other energy phenomena or waves such as light or sound.

Example: According to modern physics, matter consists of various types of particles, each with mass and size. The most familiar examples of material particles are the electron, the proton, and the neutron. ]]> 2018-01-19 09:30:18 UTC https://padlet.com/11takakin1/1eqja5hhbqyx/wish/222707460 11takakin1 https://padlet.com/11takakin1/1eqja5hhbqyx/wish/222707462 Meaning: the energy of interacting bodies or particles in a closed system remains constant

Example: when a pendulum swings upward, kinetic energy is converted to potential energy. When the pendulum stops briefly at the top of its swing, the kinetic energy is zero, and all the energy of the system is in potential energy. When the pendulum swings back down, the potential energy is converted back into kinetic energy. At all times, the sum of potential and kinetic energy is constant.]]> 2018-01-19 09:30:19 UTC https://padlet.com/11takakin1/1eqja5hhbqyx/wish/222707462 11takakin1 https://padlet.com/11takakin1/1eqja5hhbqyx/wish/224089685 Meaning: In the physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the energy associated with the motion and position of an object.

Formula: Kinetic energy+potential energy=mechanical energy

Example: a brick held at a vertical position above the ground or zero height position]]> 2018-01-24 05:49:59 UTC https://padlet.com/11takakin1/1eqja5hhbqyx/wish/224089685 11takakin1 https://padlet.com/11takakin1/1eqja5hhbqyx/wish/224090070 Meaning: refers to the internal energy present in a system due to its temperature

Formula: you can see from the imagine below

Example: Thermal energy is an example of kinetic energy, as it is due to the motion of particles, with motion being the key.]]> 2018-01-24 05:53:46 UTC https://padlet.com/11takakin1/1eqja5hhbqyx/wish/224090070 11takakin1 https://padlet.com/11takakin1/1eqja5hhbqyx/wish/224091206 Meaning: is the energy newly derived from electric potential energy or kinetic energy

Formula:  P = E ⁄ t where power P is in watts, Power P = work / time (W ⁄ t). Energy E is in joules, and time t is in seconds.

Example: 

• Lightning.
• Electrical charges moving through a wire or electricity.

Chemical energy may be released during chemical reaction, often in the form of heat; such reactions are called exothermic.

Example: coal - combustion reaction converts chemical energy into light and heat. wood - combustion reaction converts chemical energy into light and heat. petroleum - can be burned to release light and heat or changed into another form of chemical energy, such as gasoline.]]> 2018-01-24 06:07:55 UTC https://padlet.com/11takakin1/1eqja5hhbqyx/wish/224091373 11takakin1 https://padlet.com/11takakin1/1eqja5hhbqyx/wish/224091816 Meaning: There are two fundamental nuclear processes considered for energy production: fission and fusion. Fission is the energetic splitting of large atoms such as Uranium or Plutonium into two smaller atoms, called fission products.
