Sledding

Since it is winter I cannot wait to sled. This year since I am in physics I want to understand sledding better by using Newton’s laws of motion.

Newton's First Law of Motion, the Law of Inertia, states that an object's velocity will not change unless it is acted on by an outside force. The greater mass or velocity an object has, the greater its inertia. For example, it takes a pretty strong push to get you and a friend on the same sled moving, but once you gather speed you'll keep going even at the bottom of the hill where the run flattens out. It takes much more force to stop you and your friend on the sled than to stop an empty sled.

Newton’s First Law is in so many simple activities in our lives, sledding just so happens to be a fun way to express the solution of how it is possible.
