Unit 5 Blog Post

For unit 5, we talked about vectors and scalars again. We talked about real life examples like number of passengers in a plane and displacement of a flight and said if they were scalars or vectors. We went over what a force and a normal force is. A force is a push or pull and a normal force is supporting force that is perpendicular to the surface the object is on. We talked about how to find the displacement of two connect lines. We learned how to use some trig for it. Some trig we learned is SIN, COS, and TAN.
TAN is opposite over adjacent.
SIN is opposite over hypotenuse.
COS is adjacent over hypotenuse.
When using the trig, we use a method to find the displacement. First, we use bureku, which is where we break all the diagonals into X and Y. Second, we add all the values together to get the sum of the resultants. (axes still independent). Third, we use ukerub, which we take x and y sums and create a new vector. The last thing we learned in class is Newton's first law. The law is "An object in motion will tend to stay in motion unless acted upon by an outside unbalanced force."  Or "An object at rest will tend to stay at rest unless acted upon by an outside unbalanced force."

In this picture, are my two little brothers. Like usual, they are basically doing nothing. They are at rest and like Newton's first law states, an object (or objects) at rest will tend to stay at rest unless acted upon by an outside unbalanced force. My brother would rest all day, but my mom (an outside force) will come and yell at them for sitting around too much and they will have to do outside and move around.
