Shoppin'

So, like every other Sunday, I was with my mom shopping at Sam's Club but this time was special because I realized that my shopping was related to physics.  As I was pushing the cart, our lessons about Newton's first, second, and third law popped into my head. From the very start, the cart was following Newton's first law of an object at rest will stay at rest until acted on by another force which happened to be me, and will stay in motion until a force is acted upon it which probably would be me or something else I may have run into.  As I was pushing the cart, I found that the second law also applied for if I found the net force and divided it by the mass of the cart, I could have calculated the acceleration.  The once again another realization, Newton's third law was taking place as well because every action has an equal and opposite reaction. As I pushed on the cart, it pushed back on me. In the end it was a great over all shopping trip because while getting food, i got to recap on what we have been learning in class.
