''Four Forces''

1) Applied force we used in class to move a cart with our finger ''pushing and pulling'' it.
     EX in life: when i go grocery shopping in Costco with my family i would push to go foward to go fast or follow my dad. I would pull if am stuck, like cart traffic or people in our way.
2) Gravitational force in class we drop a index card and a ball to the ground and the question was what is making both objects move. Group thought ''gravity''.
     EX in life: throwing food away in the trash in east boston high we throw food away with the tray and land with other trash.
3) Normal force  in class there are two things a tape roll and a pencil on a desk we have to explain why these two things are not falling to the ground. I thought the desk can be strong enough to hold them up.
     EX in life: i would leave my laptop on my desk.
4) Tension force in class we have a barbie and a string if we hold the rubber band it will not fall and pulling the cart across the desk using the string. Because it is a pulling force deals for ex string.
     EX in life: when i was younger i use to have this yoyo called ''yoyo ball'' i holded the string it did not fall to the ground unless i threw it hard.
