200 Word Synopsis
The world is full of movement, from speeding cars to airplanes flying through the air. Along with movement also come collisions. Newton recognized that movement is a basic property of the universe, and he described movement in terms of speed, direction, and mass in his equation F=ma. Newton also recognized friction, which opposes motion. The legacy from Galileo and Newton is that forces change motion. Apply a force and the object will change speed or direction. But apply no force and the object stays moving at constant speed (which might be zero) and direction.
