This video should teach you about Newton's first law.
In this video about Newton's first law, we use experiments to show Newton's first law. First we use the egg drop experiment. Then we pull a piece of paper from under a paper towel tube. Next we will show a scooter getting stopped by a fence, and finally we show a soccer ball getting stopped by friction. These experiments show that an object at rest will stay at rest and an object in motion will stay in motion with the same velocity unless acted upon by an unblanced force.
