Science 8

Energy definition:

• Is everything that can produce a change in matter.
• Energy produced by luminous source.
• Is the transfer of thermal energy from one type of matter with a higher temperature to another type of matter with a lower temperature.
• Has got kinetic energy. It originates from something vibrating. Is movement.

Light definition:

• Is everything that can produce a change in matter.
• Energy is emmited from luminous sources and we can perceive it with our eyes.
• Is the transfer of thermal energy from one type of matter with a higher temperature to another type of matter with a lower temperature.
• Has got kinetic energy. It originates from something vibrating. Is movement.

Temperature definition:

• Is everything that can produce a change in matter.
• Everything conteins a certain amount of thermal energy that we can measure.
• Is the transfer of thermal energy from one type of matter with a higher temperature to another type of matter with a lower temperature.
• Has got kinetic energy. It originates from something vibrating. Is movement.
