The Dark History of Matches
When we began mass-producing matches in the 1800s, workers in the factories started dying mysteriously. The history of our sparking little flame-sticks is darker than you think.

Newton's Three Laws of Motion
Mr. Andersen defines Newton's three laws of motion. He describes how the first law relates to inertia, how the second law relates to mass and acceleration, and how the third law allows a rocket to launch.

The ONE thing your teacher is NOT telling you that will simply forces!
Forces are all around us and are the reason why objects accelerate (speed up, slow down or change direction)! Forces can either be balanced or unbalanced. When the forces are balanced, the net force is 0 and the object's motion will not...
