Four Forces

There were 4 forms of forces we talked about today in class, the first one was 

1. Applied Force (Fapp) is when you make contact with an object to make it move. So for example, today I had a ball. The ball needed force to move it which i applied myself! That would be the definition of Applied Force. 
2. Gravitational Force (Fg) is when gravity takes control over the object. So for example, today i used gravitational force by jumping, and the gravitational force pulled me to the ground! That would be the definition of Gravitational Force.
3. Normal Force (FN) is when an object requires no force. For example, today I came home to find my laptop sitting on my desk. That required Normal Force. 
4. Tension Force (FT) is when the force has a type of pull to it that requires back spring. For example, today i used a scrunci today to basically explain a bun and i pulled the scrunchi to my wrist a couple times. The tension force pulled the band back on my wrist.
