Forces explain why objects move, stop, speed up, slow down, or change direction. In the source lessons, forces are measured in newtons (N) using a newton meter and often represented using force arrows.
Forces can be grouped as contact or non-contact forces. Real systems usually involve multiple forces acting at once, so analyzing the Resultant Force is important.
