Newton's Laws

Newton's Laws describe how objects move and interact. First, an object stays still or moves at the same speed unless a force changes that—like a pushing or pulling. Second, the harder you push, the faster it accelerates, depending on its mass. Third, for every action, there's an equal and opposite reaction—like a rocket pushing gases down to move upward. These principles explain everyday motion, from driving a car to throwing a ball, and are fundamental to understanding physics and how the universe works.
