<human>:  Can you explain why Newton's law of motion is important?
<bot>: Newton's law of motion is a fundamental law of physics that helps explain and predict the motion of objects. This law states that an object in motion will stay in motion, and an object at rest will remain at rest, unless acted on by an external force. This law is important because it serves as the basis for the understanding of forces and their effects on objects. It also provides a framework to predict the behavior of objects in a variety of situations, and helps explain why certain motions take place.
