Final answer:
When a car window is hit with a baseball, it breaks due to the force of the impact. This demonstrates Newton's third law of motion.
Step-by-step explanation:
When a car window is hit with a baseball, it breaks due to the force exerted by the baseball. This is an example of the principle of force and motion, specifically Newton's third law of motion. According to Newton's third law, when the baseball hits the window, it exerts a force on the window, and in return, the window exerts an equal and opposite force on the baseball. The force of the impact causes the window to shatter into many pieces.
