Post #10 - Forces

The picture on the left is a picture of a piece of paper underneath my wallet. Today in class we learned about forces. Newton's Law aka law of inertia states that objects at rest will tend to stay at rest, unless acted upon by an outside force. In other words, an object staying still will continue to stay still unless outside force is acted upon it. I can show that this law is true because I pulled the paper back really fast and the wallet stayed in its initial position.

 

In the picture above, I rolled a baseball to prove the law of inertia. Objects in motion will tend to stay in motion, unless acted upon by an outside force. In this case the force is normal force. Normal force is the supporting force that is perpendicular to the surface the object is on. The normal force causes the ball to slow down and eventually come to a complete stop. 

We also went over vector readings and applying trigonometry to solving the vectors.
