What I Am Thankful For In Physics

So far this year in physics we learned about things like momentum, motion, and vectors.  But the thing I am most thankful for is Newton's first law.  An object in motion tends to stay in motion unless acted upon by an unbalanced outside force.  The reason why I like this is because it can apply to sports.  For example in baseball and football when the ball is hit by either a football or by a bat, force is applied to it causing it to accelerate.   If there wasn't an unbalanced and outside force called gravity the ball would keep flying and flying.  But because of gravity the ball falls.
