I went sledding with my friends. On the front of the sled there is a handle. One friend started pulling the handle with me on it down the hill. My other friend came up behind and pushed the sled really hard. My friend pulling the sled flew over and fell on me as we were going down the hill. This is a good example of Newton's 2nd law of motion because one friend was pushing and one was pulling the sled which created a change in speed.
