Why does a soccer ball stay still, then speed away when you kick it? First law: inertia means its motion stays unchanged unless an unbalanced force acts. Second law: a stronger kick gives more acceleration, but more mass gives less. That's F = ma. Then the kick turns into a two-way push. Third law: your foot and the ball exert equal and opposite forces on different objects. Because Newton's three laws explain resistance, acceleration, and the ball pushing back.
