How to Science: a blog
Hello, this is a quick post about density. What it is and how it affects earth.
So let's start with what density is. Density is how much matter can fit into a cetain amount of spacer , or how many atoms is in a substance. This is present when you put multiple substances in a container. The more dense things witll float to the bottom while the least dense things will go to the top of the container.
Now I'm going to give a quick explanation of convection currents because they relate directly to density. Now a convenction current is a simple concept that I'm pretty sure you've heard of before. A convection current is when hot things rise and cold things sink. This applies to wind ocean currents and tectonics. Examples would be hot air rising and cold air sinking, hot water rising and cold water sinking, and finally hot magma in the earth rising and cold magma sinking.
I hope you enjoyed this short post I might do more quick posts in the future goodbye.
It seems that I have been given the assignment to write about the difference between potential and kinetic energy. So I will start with what energy is I talked a little about energy in my last post Force vs. Energy, But I didn't go into great detail.
So the first thing that we need to know is what is kinetic energy. Well this isn't that hard you probably learned it in 5th grade science class, well at least the basic definition. Kinetic energy is motion energy, so if I pushed a ball and it rolled across the ground it would have kinetic energy.
Potential energy is also a simple one. Potential energy is stored energy or energy with potential.
An example of this would be like if you had a box sitting on a shelf that's not moving; the box would have potential energy.
This is a fun website you can visit to play around with a skater; it allows you to see the potential and kinetic energy as he moves and provides a good visual.
There are multiple kinds of both potential and kinetic energy here are some of both
Most of the kinetic energy types are self explanitory except for radiant. Radiant kinetic energy is when something is given of and is most common in tempature. An example of radiant energy would be like a campfire, microwave, x-rays, etc.

Potential energy is more complex though gravitational is quite simple so I will refrain from explaining. If anyone wants it explained just comment and I will.
chemical potential energy is potential energy that is expressed during a chemical reaction. For example a handwarmer producing heat.
Elastic potential energy relates to somethings elasticity like a rubber band. The way something would gain elastic potential energy would involve the object or mabye a person being stretched or compressed (which basically means squished). So if I had a rubberband and wanted to give it more elastic potential energy I would have to stretch it.
Magnetic potential energy involves...get this...Magnets.
I have been assigned to write this blog post since this is a science project so I will do my best to explain this topic.
First we have to understand what force and energy are. The definition of a force is a push or a pull that causes a change in the motion of an object,and the definition of energy is the capacity or ability to do work. The difference between them is that a force is what causes something to move.
Where energy is a property of an object depending on whether the object is in motion or not.

The relation between the two is that you can’t have force without energy, but you can have energy without force. Energy is always present so in reality there is no way to have zero energy, but theoretically you can’t have force without energy.
If I were to apply force to an object like a ball, previously the ball would have potential energy because it wasn’t moving so it was storing energy. Therefore if the ball starts moving in result to me pushing it the potential energy turns into kinetic energy.
The force was present when I pushed the ball, but before there was no force. Where energy was present the entire time although in different forms it was present.
This is a short little video that goes more in depth about Forces vs, energy. Some of the concepts in this video weren't mentioned in my post but they will help comprehension all the same.
P.S This is my first post so it is not the best, just stay with me and I will make these better as I go.
