La energía cinética se define como:
⇒
mi
k
=
1
2 metro v2
Dado que la masa del péndulo no cambiará, la única forma de que cambie la energía cinética es que cambie la velocidad del péndulo. La energía cinética es máxima cuando la velocidad es máxima. Esto ocurre en la parte inferior del péndulo.

.
Si la energía cinética es más alta en la parte inferior del péndulo, entonces es donde la energía potencial es la más baja. Entonces, la energía potencial sería más alta cuando el péndulo esté en su punto más alto a cada lado de su movimiento donde está estacionario por un instante. Este es el punto donde toda la energía cinética se ha convertido en energía potencial (

1. Answer: What I learned from my Local Health department website is that if I were to help an area of need I should start by picking up any trash and litter, I should also help recycling to help the environment. I also learned that I should recreate the area by seeing if it needs extra biking trails or exercise trails, I should also see if there needs to be any walking paths so people can walk, I should also add little riddles on signs and spread them throughout the area so they could also do a little bit of walking. There is also smoking problems so I think that putting a sign that ban's smoking in that area. I feel like the area should also check to see if anybody is sick so they wont get anybody else infected and keep the area clean and healthy.
2. Answer: I learned that we should care for ourselves and the things around us to have a better environment and a healthier life. If we don't do so the world won't be healthy and neither will we be.
3. Answer: The plan I came up with to help with health and safety is to make sure that we have a stand where we check to see if anybody is sick, the safety is where if kids don't have knee pads or anything to protect themselves we have another stand where we sell all of that only for a dollar, we also have a first aid kit. The reason why I chose to address the issue is because I want to make the world a better place no matter what. Me and my family would love to help out to see the children smiling in a clean environment. I will try my best with all I got and pick up trash, recycle, and help as much as possible. Maybe when I'm old enough so I can be mature and the place would most likely be a park or just a random area and turn it into something nice.
4. Answer: How I plan to monitor and measure my progress is a before and after picture! How I put up smaller tasks to accomplish, schedules, deadlines, and manage time is just by playing little mini games that have a timer so we can have fun and get more done.
It's definitely letter A. Mononucleosis
It’s saddle hope this helps !!
From what I learned it health class it’s 60%
