Hey people, today i'll be talking about energy and the many types of energy. First, energy is what is used to make electricity and it's also what you are using right now. There are two types of energy, there is kinetic energy and potential energy. Kinetic energy is when something is in motion. Mass and speed play a big part in kinetic energy.
The other type of energy is Potential energy. Potential energy is when something is having the potential of being put into motion. An example for Kinetic energy is a ball being kicked and is put into motion. An example for Potential energy is a boulder sitting on the point of a cliff and is having a potential to fall off of the cliff point. Mass for Kinetic energy has a big part because the bigger it is, also helps with the speed of the object. Mass has the same effect with Potential energy.
Kinetic energy depends on speed because it determines on how fast the object goes. An example for Kinetic energy transferring from one object to another is a bowling ball being put into motion and hitting a bowling pin and the bowling pin being put into motion by the bowling ball, which making the pin hit another pin and then another pin and so forth, creating the so called domino effect.
That's all for today people see you next time!
Hey guys, today i'll be talking about states of matter, but first you have to know what matter is. Matter is anything that has mass and takes up space. The three most commonly known states of matter are solids, liquids, and gases. Except those aren't the only states of matter, there is another called plasma. There are many different types of plasma. Some examples are: lightning, fire, and neon. The most common plasma on Earth is lightning.
Matter can also change to different states because of temperature and also because of pressure. When matter changes states it only changes physically, not chemically. An example is ice going from a solid to water, a liquid. Even though its form changed, its physical properties were the only thing that changed with it. Matter's chemical properties never change, they always stay the same.
Also, everything has their own melting and boiling points. A melting point is which a solid becomes a liquid. An example of a melting point is ice. Another part that is included in the states of matter is something called heat of fusion. Heat of fusion is the energy required to change a substance like a solid to a liquid, without changing its temperature. This energy breaks down the solid bonds, but it leaves a significant amount of energy associated with the molecular forces of the liquid state.
That's all for today people see you next week!
