Best Alternative Energy Source: Wind Turbines

I believe wind turbines are the best energy source. Wind is free so we can use as much as we need. The energy that is produced does not emit harmful gases and is renewable. All though wind turbines are very good for the environment, there are also downfalls. When the turbines are being built, the factory releases gases. Also, the wind speeds aren't always constant. A solution to that would be to move to a place where there is a lot of wind.
Even though wind turbines have a few downfalls, I still believe they are good because they don't emit harmful gases.

Projectile Motion With A Watering Hose

When I was watering plants, I noticed that the water curved after a while. It didn't spray straight out. That is because of gravity. When the water was squirted in the air, the force that was acting upon it was gravity. It was the only force affecting the water.

How Physics Impacts My Life

Q: How does physics impact my everyday life?

A: When I was going home yesterday, I noticed that cars were passing the bus I was in. I came to the conclusion that we were either driving at a constant speed. The other cars were accelerating their speed while we were driving at a constant speed. Physics impacts my everyday life because I can tell when the car is driving too slow or too fast by looking at the other cars. You can also look at the landscape and see if it's whipping by and you know you're going too fast and that you should slow down so you don't get a ticket. 

What I Think Physics Is

     I believe physics describes how matter and energy and how they are related. Matter is said to be what makes up objects. Energy comes in many forms, such as light, sound, and heat. Physics is also used to learn about nature and how the universe works. 

     Physics is different than other sciences, such as biology and chemistry. Biology explains life. It talks about the millions of cells that make up organisms. Chemistry deals with atoms and molecules. Physics is different because it talks about matter, energy, and force and how they work in real life.
